Mutation-acyclicity in rank four is decidable but not semialgebraic
Kymani T. K. Armstrong-Williams, Edward Hirst, Blake Jackson +1
We prove that mutation-acyclicity of quivers on four vertices is decidable. If a four-vertex quiver is mutation-acyclic, then some sequence of mutations takes it to an acyclic…

Machine Learning Mutation-Acyclicity of Quivers
Kymani T. K. Armstrong-Williams, Edward Hirst, Blake Jackson +1
Machine learning (ML) has emerged as a powerful tool in mathematical research in recent years. This paper applies ML techniques to the study of quivers -- a type of directed multig…
