Some reverse Hilbert's type inequalities involving series of non-negative terms are established by the use of the technique of real analysis, which pr......

We generalize the notion "k-Mittag-Leffler function", establish some integral transforms of the generalized k-Mittag-Leffler function, and derive seve......

A space X is said to be neighborhood star-Menger if for every sequence (U-n : n is an element of N) of open covers of X one can choose finite A(n) sub......

We study certain curvature properties of Kenmotsu manifolds with respect to the quarter-symmetric metric connection. First we consider Ricci semisymme......

We define the product shaped hypersurfaces in Lorentz space forms by imposing the shape operator to be product type. Based on the classification of th......

Let FP(X) be the free paratopological group over a topological space X. For each nonnegative integer n is an element of N, denote by FPn(X) the subset......

A graph G is fractional ID-[a, b]-factor-critical if G - I has a fractional [a, b]-factor for every independent set I of G. We extend a result of Zhou......

We discuss the sharpness of the bound of the Fekete-Szeg functional for close-to-convex functions with respect to convex functions. We also briefly co......

A ring R is uniquely pi-clean if the power of every element can be uniquely written as the sum of an idempotent and a unit. We prove that a ring R is ......
