## 金融代写|金融数值计算代写Market Risk, Numerical Analysis for Finance代考|Sequences and series of real or complex numbers

A sequence is a set of numbers $u_1, u_2, u_3, \ldots$, in a definite order of arrangement, that is, a map $u: \mathbb{N} \rightarrow \mathbb{R}$ or $u: \mathbb{N} \rightarrow \mathbb{C}$, formed according to a certain rule. Each number in the sequence is called term; $u_n$ is called the $n^{\text {th }}$ term. The sequence is called finite or infinite, according to the number of terms. The sequence $u_1, u_2, u_3, \ldots$, when considered as a function, is also designated as $\left(u_n\right)_{n \in \mathbb{N}}$ or briefly $\left(u_n\right)$.

Definition 2.1. The real or complex number $\ell$ is called the limit of the infinite sequence $\left(u_n\right)$ if, for any positive number $\varepsilon$, there exists a positive number $n_{\varepsilon}$, depending on $\varepsilon$, such that $\left|u_n-\ell\right|<\varepsilon$ for all integers $n>n_{\varepsilon}$. In such a case, we denote:
$$\lim {n \rightarrow \infty} u_n=\ell .$$ Given a sequence $\left(u_n\right)$, we say that its associated infinite series $\sum{n=1}^{\infty} u_n$ :
(i) converges, when it exists the limit:
$$\lim {n \rightarrow \infty} \sum{k=1}^n u_k:=S=\sum_{n=1}^{\infty} u_n ;$$
(ii) diverges, when the limit of the partial sums $\sum_{k=1}^n u_k$ does not exist.

## 金融代写|金融数值计算代写Market Risk, Numerical Analysis for Finance代考|Sequences of functions

Given a real interval $[a, b]$, we denote $\mathscr{F}([a, b])$ the collection of all real functions defined on $[a, b]$ :
$$\mathscr{F}([a, b])={f \mid f:[a, b] \rightarrow \mathbb{R}} .$$
Definition 2.2. A sequence of functions with domain $[a, b]$ is a sequence of elements of $\mathscr{F}([a, b])$.

Example 2.3. Functions $f_n(x)=x^n$, where $x \in[0,1]$, form a sequence of functions in $\mathscr{F}([0,1])$.

Let us analyse what happens when $n \rightarrow \infty$. It is easy to realise that a sequence of continuous functions may converge to a non-continuous function. Indeed, for the sequence of functions in Example 2.3, it holds:

Thus, even if every function of the sequence $f_n(x)=x^n$ is continuous, the limit function $f(x)$, defined below, may not be continuous:
$$f(x):=\lim _{n \rightarrow \infty} f_n(x) .$$
The convergence of a sequence of functions, like that of Example 2.3, is called simple convergence. We now provide its rigorous definition.

Definition 2.4. If $\left(f_n\right)$ is a sequence of functions in $I \subset[a, b]$ and $f$ is a real function on $I$, then $f_n$ pointwise converges to $f$ if, for any $x \in I$, there exists the limit of the real sequence $\left(f_n(x)\right)$ and its value is $f(x)$ :
$$\lim _{n \rightarrow \infty} f_n(x)=f(x) .$$
Pointwise convergence is denoted as follows:
$$f_n \stackrel{I}{\rightarrow} f .$$

## 金融代写|金融数值计算代写Market Risk, Numerical Analysis for Finance代考|Limits of functions

A vector function is a function $f$ of the form $f: A \rightarrow \mathbb{R}^m$, where $A \subset \mathbb{R}^n$. Since $f(\boldsymbol{x}) \in \mathbb{R}^m$ for each $\boldsymbol{x} \in A$, then there are $m$ functions $f_j: A \rightarrow \mathbb{R}$, called component functions of $f$, such that:
$$f(\boldsymbol{x})=\left(f_1(\boldsymbol{x}), \ldots, f_m(\boldsymbol{x})\right) \quad \text { for each } \quad \boldsymbol{x} \in A .$$
When $m=1$, function $f$ has only one component and we call $f$ real-valued. If $f=\left(f_1, \ldots, f_m\right)$ is a vector function, where the components $f_j$ have intrinsic domains, then the maximal domain of $f$ is defined to be the intersection of the domains of all components $f_j$.
To set up a notation for the algebra of vector functions, let $E \subset \mathbb{R}^n$ and let $f, g: E \rightarrow \mathbb{R}^m$. For each $x \in E$, the following operations can be defined. The scalar multiple of $\alpha \in \mathbb{R}$ by $f$ is given by:
$$(\alpha f)(\boldsymbol{x}):=\alpha f(\boldsymbol{x}) .$$
The sum of $f$ and $g$ is obtained as:
$$(f+g)(\boldsymbol{x}):=f(\boldsymbol{x})+g(\boldsymbol{x}) .$$
The (Euclidean) dot product of $f$ and $y$ is constructed as:
$$(f \cdot g)(\boldsymbol{x}):=f(\boldsymbol{x}) \cdot g(\boldsymbol{x}) .$$

The (Euclidean) dot product of $f$ and $y$ is constructed as:
$$(f \cdot g)(\boldsymbol{x}):=f(\boldsymbol{x}) \cdot g(\boldsymbol{x})$$

Definition 1.22. Let $n, m \in \mathbb{N}$ and $\boldsymbol{a} \in \mathbb{R}^n$, let $V$ be an open set containing $\boldsymbol{a}$ and let $f: V \backslash{\boldsymbol{a}} \rightarrow \mathbb{R}^m$. Then, $f(\boldsymbol{x})$ is said to converge to $\boldsymbol{L}$, as $\boldsymbol{x}$ approaches $\boldsymbol{a}$, if and only if for every $\varepsilon>0$ there exists a positive $\delta$ (that in general depends on $\varepsilon, f, V, \boldsymbol{a})$ such that:
$$0<|\boldsymbol{x}-\boldsymbol{a}|<\delta \Longrightarrow|f(\boldsymbol{x})-\boldsymbol{L}|<\varepsilon .$$
In this case we write:
$$\lim _{\boldsymbol{x} \rightarrow \boldsymbol{a}} f(\boldsymbol{x})=\boldsymbol{L}$$
and call $\boldsymbol{L}$ the limit of $f(\boldsymbol{x})$ as $\boldsymbol{x}$ approaches $\boldsymbol{a}$. Using the analogy between the norm on $\mathbb{R}^n$ and the absolute value on $\mathbb{R}$, it is possible to extend a great part of the one-dimensional theory on limits of functions to the Euclidean space setting.

## 金融代写|金融数值计算代写Market Risk, Numerical Analysis for Finance代考|Euclidean space

If $n \in \mathbb{N}$, we use the symbol $\mathbb{R}^n$ to indicate the Cartesian ${ }^1$ product of $n$ copies of $\mathbb{R}$ with itself, i.e.:
$$\mathbb{R}^n:=\left{\left(x_1, x_2, \ldots, x_n\right) \mid x_j \in \mathbb{R} \text { for } j=1,2, \ldots, n\right} .$$
The concept of Euclidean ${ }^2$ space is not limited to the set $\mathbb{R}^n$, but it also includes the so-called Euclidean inner product, introduced in Definition 1.1. The integer $n$ is called dimension of $\mathbb{R}^n$, the elements $\boldsymbol{x}=\left(x_1, x_2, \ldots, x_n\right)$ of $\mathbb{R}^n$ are called points, or vectors or ordered $n$-tuples, while $x_j, j=1, \ldots, n$, are the coordinates, or components, of $\boldsymbol{x}$. Vectors $\boldsymbol{x}$ and $\boldsymbol{y}$ are equal if $x_j=y_j$ for $j=1,2, \ldots, n$. The zero vector is the vector whose components are null, that is, $0:=(0,0, \ldots, 0)$. In low dimension situations, i.e. for $n=2$ or $n=3$, we will write $\boldsymbol{x}=(x, y)$ and $\boldsymbol{x}=(x, y, z)$, respectively.
For our purposes, that is extending differential calculus to functions of several variables, we need to define an algebraic structure in $\mathbb{R}^n$. This is done by introducing operations in $\mathbb{R}^n$.

Definition 1.1. Let $\boldsymbol{x}=\left(x_1, x_2, \ldots, x_n\right), \boldsymbol{y}=\left(y_1, y_2, \ldots, y_n\right) \in \mathbb{R}^n$ and $\alpha \in \mathbb{R}$.
(i) The sum of $\boldsymbol{x}$ and $\boldsymbol{y}$ is the vector:
$$\boldsymbol{x}+\boldsymbol{y}:=\left(x_1+y_1, x_2+y_2, \ldots, x_n+y_n\right)$$

(ii) The difference of $\boldsymbol{x}$ and $\boldsymbol{y}$ is the vector:
$$\boldsymbol{x}-\boldsymbol{y}:=\left(x_1-y_1, x_2-y_2, \ldots, x_n-y_n\right) ;$$
(iii) The $\alpha$-multiple of $\boldsymbol{x}$ is the vector:
$$\alpha \boldsymbol{x}=\left(\alpha x_1, \alpha x_2, \ldots, \alpha x_n\right)$$
(iv) The Euclidean inner product of $\boldsymbol{x}$ and $\boldsymbol{y}$ is the real number:
$$\boldsymbol{x} \cdot \boldsymbol{y}:=x_1 y_1+x_2 y_2+\ldots+x_n y_n$$

## 金融代写|金融数值计算代写Market Risk, Numerical Analysis for Finance代考|Topology of R

Topology, that is the description of the relations among subsets of $\mathbb{R}^n$, is based on the concept of open and closed sets, that generalises the notion of open and closed intervals. After introducing these concepts, we state their most basic properties. The first step is the natural generalisation of intervals in $\mathbb{R}^n$.

Definition 1.13. Open and closed balls are defined as follows:
(i) $\forall r>0$, the open ball, centered at $\boldsymbol{a}$, of radius $r$, is the set of points:
$$B_r(\boldsymbol{a}):=\left{\boldsymbol{x} \in \mathbb{R}^n \mid|\boldsymbol{x}-\boldsymbol{a}|<r\right} ;$$
(ii) $\forall r \geq 0$, the closed ball, centered at $a$, of radius $r$, is the set of points:
$$\bar{B}_r(\boldsymbol{a})\left{\boldsymbol{x} \in \mathbb{R}^n \mid|\boldsymbol{x}-\boldsymbol{a}| \leq r\right} .$$
Note that, when $n=1$, the open ball centered at $\boldsymbol{a}$ of radius $r$ is the open interval $(a-r, a+r)$, and the corresponding closed ball is the closed interval $[a-r, a+r]$. Here we adopt the convention of representing open balls as dashed circumferences, while closed balls are drawn as solid circumferences, as shown in Figure 1.4.

To generalise the concept of open and closed intervals even further, observe that each element of an open interval $I$ lies inside $I$, i.e., it is surrounded by other points in $I$. Although closed intervals do not satisfy this property, their complements do. Accordingly, we give the following Definition 1.14, in which ” $\subset$ ” denotes non-strict inclusion (and analogously for ” $\supset “$ “).
