Differentiably simple rings and ring extensions defined by $p$ -basis

Celia del Buey de Andrés, Diego Sulca, Orlando E. Villamayor

We review the concept of differentiably simple ring and we give a new proof of Harper's Theorem on the characterization of Noetherian differentiably simple rings in positive charac…

On the simplification of singularities by blowing up at equimultiple centers

Orlando E. Villamayor U

Resolution of singularities of varieties over fields of characteristic zero can be proved by using the multiplicity as main invariant. The proof of this result leads to new questio…
