Digital roots of numbers have several interesting properties, most of which are well-known. In this paper, our goal is to prove some lesser known results concer
Let f(z) be a function transcendental and meromorphic in the plane of growth order less than 1. This paper focuses on discuss and estimate the number of the zer
Faith-Menal counter example is an example (unique) of a right John’s ring which is not right artinian In this paper we show that the ring T which considered as
We use C*-algebras to determine non-propagation estimates for a certain class of generalized Schr?dinger operators acting on L2(x) , where X is a locally compac
For the (2 + 1)-dimensional Broer-Kaup system, we study the corresponding Lie symmetry groups, and obtain the symmetry group theorem and the Backlund transforma
