Involving an extended 1-cocycle condition, we first define a coproduct on the space of bi-decorated planar rooted forests to equip it with a left coun......

Let a and b be two distinct fixed positive integers such that min{a, b} > 1. First, we correct an oversight from [12]. Then, we show that the equat......

By using Nevanlinna theory and linear algebra, we show that the number one is a lower bound of the hyper-order of any meromorphic solution of a non-li......

In this paper, we consider a class of pseudo-parabolic equation, which was studied extensively in recent years, and the main results on blow-up depend......

Topological properties of compactly-fibered coset spaces are investigated. It is proved that for a compactly-fibered coset space X with Nag(X) <= t......

In this paper we introduce a new class of rings whose elements are a sum of a central and a unit element, namely a ring R is called CU if each element......
