For a weakly multiplicative sequence of random variables {X n} the almost sure uniform convergence of the random trigonometric series ∑ ∞ n = - ∞ a n e int X n (ω) is results are then used to prove the sample continuity of a weakly stationary process under certain conditions which are weaker than the usual conditions.

With these tools, we are able to give in full generality necessary and sufficient conditions for convergence of random Fourier series. These conditions can be formulated in words by saying that convergence is equivalent to the finiteness of (a proper generalization of) a certain “entropy integral”.

A necessary and sufficient condition for an isolated singular point a of a function f(z) to be a pole of order n is that the principal part of f(z) at z = a contain exactly n terms.

In other words, if an isolated singular point a of a function f(z) is a pole of order n the Laurent expansion will have the form. For Fourier series in a rearranged trigonometric system certain properties of the Fourier series in the trigonometric system, taken in the usual order, do not hold.

For example, there is a continuous function such that its Fourier series after a certain rearrangement diverges almost-everywhere (see [KoMe]. In mathematics, the study of interchange of limiting operations is one of the major concerns of mathematical analysis, in that two given limiting operations, say L and M, cannot be assumed to give the same result when applied in either order.

One of the historical sources for this theory is the study of trigonometric series. Marcus and G. Pisier, Necessary and sufficient conditions for the uniform convergence of random trigonometric series, Lecture Notes Series, vol.

50, Aarhus Universitet, Matematisk Institut, Aarhus, Lecture / MR There are many known sufficient conditions for the Fourier series of a function to converge at a given point x, for example if the function is differentiable at a jump discontinuity does not pose a problem: if the function has left and right derivatives at x, then the Fourier series converges to the average of the left and right limits (but see Gibbs phenomenon).

In the mathematical field of analysis, uniform convergence is a mode of convergence of functions stronger than pointwise convergence.A sequence of functions converges uniformly to a limiting function on a set if, given any arbitrarily small positive number, a number can be found such that each of the functions, +, +, differ from by no more than at every point in.

When β = 2, the equivalence and may be deduced from, p. since each is necessary and sufficient condition for a random variable with cdf F ˜ (x) to be in the domain of attraction of a normal distribution, where F (x) = F ˜ (x) − F ˜ (− x), x ≥ 0.

It is important to note that for other notions of stochastic convergence (in probability, almost sure and in mean-square), the convergence of each single entry of the random vector is necessary and sufficient for their joint convergence, that is, for the convergence of the vector as a whole.

Instead, for convergence in distribution, the individual convergence of the entries of the vector is. The crucial condition which distinguishes uniform convergence from pointwise convergence of a sequence of functions is that the number N N N in the definition depends only on ϵ \epsilon ϵ and not on x x x.

It follows that every uniformly convergent sequence of functions is pointwise convergent to the same limit function, thus uniform. ON RANDOM FOURIER SERIES 55 Note that the minimal assumption EIXIl/a convergence of S(t) at every fixed t is also sufficient for the a.s.

Deﬁnition The random variables Y 1,Y topic in its own right and you will ﬁnd it in both Lehmann’s book and Ferguson’s book if you are interested. Answer: Since uniform convergence is equivalent to convergence in the uniform metric, we can answer this question by computing $\du(f_n, f)$ and checking if $\du(f_n, f)\to0$.

We have, by definition \[ \du(f_n, f) = \sup_{0\leq x\lt 1}|x^n - 0| =\sup_{0\leq x\lt 1} x^n = 1. A power series, for example, is convergent for all values of x in a certain interval, called the interval of convergence, and divergent for all values of x outside this interval.

Concept of uniform convergence. When working with series whose terms are functions of some variable x the necessity arises for differentiating them term by term. ory of almost periodic functions, the necessary and sufficient condition for a series of the form (A2) to be the Fourier series of a function in AP(R,C)is its summability by a linear method (Cesaro, Fejér, Bochner), with respect to the uniform convergence on R.
