Framed Parabolic sheaves on a trinion

Algebraic Geometry 2023-02-03 v1

Abstract

We consider for structure groups SU(n)SL(n,C){\rm SU}(n)\,\subset\, {\rm SL}(n,\mathbb C) a densely defined toric structure on the moduli of framed parabolic sheaves on a three-punctured sphere, which degenerates to an actual toric structure. In combination with previous degeneration results, these extend to similar moduli for arbitrary Riemann surfaces.
