A class of singularly perturbed problems for the nonlinear elliptic equations is considered. Under suitable conditions, using the theory of differential inequal
This paper presents the popularization of the weighting of Chebyshev's inequality and discusses the relation between this popularization and some famous ine
The purpose of this note is to establish a general representation of Hankel matrices of Bell numbers and the convoluted Bell numbers. As a special ease, the res
