Denote by T and I-alpha the bilinear Calderon-Zygmund operators and bilinear fractional integrals, respectively. In this paper, it is proved that if b......

A trajectory-harp is a variation of geodesics associated with a trajectory. We estimate how trajectories for Kahler magnetic fields go away from their......

The main purpose of this investigation is to find several coefficient inequalities and a sufficient condition for q-starlike functions which are assoc......

In this paper we prove that a finite group in which all non-nilpotent maximal subgroups are normal must have a Sylow tower, which improves Theorem 1.3......

The aim of this paper is to investigate the decompositional structure of generalized fractional integral operators whose kernels are the generalized h......

In this paper, we introduce the truncated Euler-Carlitz numbers as analogues of hypergeometric Euler numbers. In a special case, Euler-Carlitz numbers......
