Contribution
It defines and explores expansions of abelian categories, providing a new framework for related mathematical arguments and applications.
Findings
Introduces the concept of expansions of abelian categories
Demonstrates applications in coherent sheaves on weighted projective lines
Provides tools for induction and reduction in category theory
Abstract
Expansions of abelian categories are introduced. These are certain functors between abelian categories and provide a tool for induction/reduction arguments. Expansions arise naturally in the study of coherent sheaves on weighted projective lines; this is illustrated by various applications.
