On the infinite dual Goldie dimension
The aim of my talk is to investigate the infinite case of the dual Goldie dimension of the right R-module R_R. First we analyze which properties of the finite Goldie dimension of a modular lattice still hold in the infinite case. Then we restrict our attention to the case of the dual Goldie dimension of R_R, showing how we can look only at maximal right ideals, instead of the whole lattice of right ideals. In the end, we study two relevant examples, computing their dual Goldie dimension and showing the difficulties that arise in passing from the finite case to the infinite one.
