Let G be a finite group and N(G)be its norm.Then N(G)is a characteristic subgroup of G which normalizes every subgroup of G.In this paper,we will study the structure of G under one of the following conditions:1)norm quotient group G/N(G)is cyclic;2)all Sy
This paper examines the existence and uniqueness of solutions for the fractional boundary value problems with integral boundary conditions.Banach\'s contraction mapping principle and Schaefer\'s fixed point theorem have been used besides topological t
