Please show all the work!!! Thank you
1. The Cantor set is one of the most famous sets in mathematics and has some rather unique properties. The Cantor set was discovered in 1874 by Henry John Stephen Smith and introduced to the world by George Cantor in 1883. The Cantor set is a set of points lying on a single closed line segment, say from [0,1]. It is constructed as follows: Start with the closed interval Co-10.1]. Remove the open...
(1) Starting with the interval [0, 1, we first take away the middle third to obtain two small intervals. The one that is taken away is (1/3.,2/3) and the two remaining intervals are [0,1/3] and [2/3, 1]. Next we take away the middle third for each of the two remaining intervals to produce four even smaller intervals. Keep taking the middle third for each of the remaining intervals, and so on forever, we wil end up with a set of...
3. Consider the Cantor set D formed by deleting the middle subinterval of length 4-* from each remaining interval at step k. (a) Prove that the length of the D is 1/2. Thus D is a fat fractal. (b) What is the box-counting dimension of D? (c) Let be the function of [0,1] which is equal to 1 on D and 0 elsewhere. It is the limit of functions which are Riemann integrable. Note that f is not Riemann integrable....

5. Consider the sample space Ω = [0, 1]. Let P be a probability function such that for any interval fa, b, P(a, b-b-a. In other words, probabilty of any interval is its length Let us start with Co [0, 1, and at nth step, we define Cn by removing an interval of length 1/3 from the middle of each interval in Cn-1 For example, C1-[0, 1/3 u [2/3,1], C2-[0,1/9)U[2/9,1/3 U [2/3,7/9 U[8/9, 1] and so on. Here is a...
Consider the sample space Ω-10, 1]. Let P be a probability function such that for any interval [a, b], P([a, b) b- a. In other words, probabilty of any interval is its length. Let us start with Co 10, 1], and at nth step, we define C, by removing an interval of length 1/3° from the middle of each interval in Cn-1. For example, G = [0, 1/3ju [2/3, 11, c2 [0, 1/9] U [2/9, 1/3] U [2/3,7/9] U [8/9,...
Let X = ℝ with the standard topology and I = [0, 1]. Let F1 be
the subset of I formed by removing the open middle third (1/3,
2/3). Then F1 = [0, 1/3]⋃[2/3, 1] Next, let F2 be the subset of F1
formed by removing the open middle thirds (1/9, 2/9) and (7/9, 8/9)
of the two components of F1. Then F2 = [0, 1/9] ⋃[2/9, 1/3] ⋃[2/3,
7/9] ⋃[8/9, 1] Continuing this manner, let Fn+1be the subset of...
Discretization, ODE solving, condition number. Consider the differential equation 5y"(x) - 2y'(x) +10y(x)0 on the interval x E [0,10] with boundary conditions y(0)2 and y (10) 3 we set up a finite difference scheme as follows. Divide [0,10] into N-10 sub-intervals, i.e. {xo, X1, [0,1,. 10. Denote xi Xo + ih (here, h- 1) and yi E y(x). Approximate the derivatives as follows X10- 2h we have the following equations representing the ODE at each point Xi ,i = 1,...
