Course overview and goals
This course follows Advanced courses in Algebra C, building on the topics covered there, we study basic properties and applications of quasi-Frobenius-regularity.
Course description and aims
Students are expected to understand the basic notion of Frobenius regularity and quasi-Frobenius-regularity. Looking through concrete examples and applications, students get acquainted with the fundamental importance of singularities in positive characteristic in current research.
Keywords
Commutative ring, Singularities, Frobenius morphisms, Witt ring.
