Let R be a ring with unity. In this paper, we introduce a new graph associated with R called the simple-intersection graph of R, denoted by GS(R). The vertices of GS(R) are the nonzero ideals of R, and two vertices are adjacent if and only if their i

A G−graded R−module is called flexible if Mg = RgMe for every g ∈ G. In this paper, we study the relationship between a flexible module and the graded ring R through different aspects. On one hand, we distinguish the flexible modules from other

Let p : M ˜ → M and p ′ : N ˜ → N be finite regular covering maps, and f , g : M → N be maps between connected compact manifolds without boundary of any codimension. A new coincidence index (the covering index) related to the covering maps

Let p : M ˜ → M and p ′ : N ˜ → N be finite regular covering maps, and f , g : ( M , K ) → ( N , L ) be maps between connected compact manifolds without boundary of any codimension that admit lifts. We introduce the relative covering Nielse

Let f, g : M → N be maps between closed orientable manifolds of the same dimension, and let $$p\,:\,\widetilde M\; \to \;M\;and\;p'\,:\,\;\widetilde N\; \to \;N$$ be finite regular covering maps. In this paper, we show that the ordinary Nielsen num

Let f , g : M → N be maps between closed smooth manifolds of the same dimension, and let p : M ˜ → M and p ′ : N ˜ → N be finite regular covering maps. If the manifolds are nonorientable, using semi-index, we introduce two new Nielsen numbe
