Homological algebra and module theory constitute a vibrant area of contemporary mathematics, interweaving concepts from algebra, topology and geometry. At its core, homological algebra studies chain ...

In this paper we show that the Rees algebra can be made into a functor on modules over a ring in a way that extends its classical definition for ideals. The Rees algebra of a module M may be computed ...

Number sequences are sets of numbers that follow a pattern or a rule. Each number in a sequence is called a term. There are some special sequences that you should recognise. The most important of ...
