Abstract
We propose a mutation formula for the general rank from a principal component \({{\,\textrm{PC}\,}}(\delta )\) of representations to another one \({{\,\textrm{PC}\,}}({\epsilon })\) for a quiver with potential. We give sufficient conditions for the formula to hold. In particular, the formula holds when any of \(\delta \) and \({\epsilon }\) is reachable. We discover several related mutation invariants.
期刊介绍:
Algebras and Representation Theory features carefully refereed papers relating, in its broadest sense, to the structure and representation theory of algebras, including Lie algebras and superalgebras, rings of differential operators, group rings and algebras, C*-algebras and Hopf algebras, with particular emphasis on quantum groups.
The journal contains high level, significant and original research papers, as well as expository survey papers written by specialists who present the state-of-the-art of well-defined subjects or subdomains. Occasionally, special issues on specific subjects are published as well, the latter allowing specialists and non-specialists to quickly get acquainted with new developments and topics within the field of rings, algebras and their applications.
