Setting the scene for Betti characters

چکیده
Finite group actions on free resolutions and modules arise naturally in many interesting examples. Understanding these amounts to describing the terms of a resolution or graded components module as representations which, non modular case, are completely determined by their characters. With this goal mind, we introduce Macaulay2 package for computing characters finite groups finitely generated over polynomial rings.

However, when oaks grow in forests they compete with each other and develop long straight trunks; they have an appearance that is totally different from the same species growing in open country. One of us, on a family holiday in Greece, collected two tiny ...
متن کاملSetting the Scene for ERP Implementation
This paper is based upon a communication model of the rationales for ERP adoption. It focusses mainly on the themes of, rationality, values, and domination that underlie the model. The potential impact on the organisations that adopt them, in terms of their mission and the people that work within them are critically examined. Conclusions reached in the paper are that risks to organisational mis...
