Yet again on two examples by Iyama and Yoshino

We give an elementary proof of Iyama-Yoshino’s classification of rigid MCM modules on Veronese embeddings in P.

On Two Examples by Iyama and Yoshino

In a recent paper Iyama and Yoshino consider two interesting examples of isolated singularities over which it is possible to classify the indecomposable maximal Cohen-Macaulay modules in terms of linear algebra data. In this paper we present two new approaches to these examples. In the first approach we give a relation with cluster categories. In the second approach we use Orlov’s result on the...

On the existence of black hole evaporation yet again

A new argument is presented confirming the point of view that a Schwarzshild black hole formed during a collapse process does not radiate.
