Functions of Two Variables Functions of two variables can be visualized in many ways: heat maps in 2D, contour curves in 2D, wireframes in 3D, surfaces in 3D. We begin by defining a function of two ...

In my recent publication on the H-function of two variables [4], the double integrals are evaluated by using the technique of known integrals. In the present study a very general type of double ...

For example, the function f (x,y) = 1 when both x and y are in the interval [0,1] and zero otherwise, is a joint density function for a pair of random variables X and Y.

This work was motivated by the fact that in the binary domain there are exactly 4 symmetric bent functions for every even n. A first study in the ternary domain shows very different properties. There ...

This Concept Schur- Convexity, first brought by Elezovic and Pecaric for describe the meanly behavior of convex functions, now extended for covering the medium of two-variable Schur- Harmonic convex ...
