Conjugate functions in two variablesNörlund meansC, γ, δ)-meansKernelestimatesThe rate of uniform approximationWe study the rate of uniform approximation by Nrlund means of the rectangular partial sums of double Fourier series of continuous functionsf(x, y), 2π-periodic in each variable. ...
The goal of the present paper is to prove that a continuous function of two variables is horizontally rigid if and only if it is of the form a+ bx + dy (a,b,d mathbbR){{a+ bx + dy (a,b,d in mathbb{R})}}. This problem also remains open in higher dimensions. The main new...
What is a continuous function? Different types (left, right, uniformly) in simple terms, with examples. Check continuity in easy steps.
Continuous Function: Definition A function is an expression or equation that expresses a relationship between one variable and another. In the equation, any x value will result in one y value. The set of x values through the function are the domain of a function. Some functions can be ...
context of purely discrete or continuous random variables. However for a mixture of discrete and continuous random variables, which arise in many interesting situations, the notions of entropy and entropy preservation have not been well understood. ...
1.In this article,some new integral inequalities of discontinuous function in two independent variables is investigated,some new results are obtained,which generalize some existing conclusions.主要研究了具有两个独立变量的不连续函数(有跳跃间断点)的一类更为广泛的新型积分不等式(Wendroff型),得出了一些新的...
Continuous random variables are discussed also in: the lecture onrandom variables; the glossary entry on theprobability density function. Multivariate generalizations of the concept are presented here: continuous random vector; random matrix. Keep reading the glossary ...
