Morita equivalences between cyclotomic KLR algebras in types ${\mathtt{C}}_{\infty }$ and ${\mathtt{A}}_{\infty }$

Chris Bowman, Robert Muth, Liron Speyer +1

We prove that level one cyclotomic KLR algebras in type ${\mathtt{C}}_{\infty }$ are graded Morita equivalent to level two cyclotomic KLR algebras in type ${\mathtt{A}}_{\infty }$. We hence…
