Abstract: A variety over a perfect field of characteristic p>0 is called globally F-regular if it is stably Frobenius split along every effective divisor. A variety over a field of characteristic zero is called globally F-regular type if its modulo p reduction is globally F-regular for almost p. In this talk, I will report a joint work with Mingshuo Zhou that moduli spaces of semi-stable parabolic bundles and generalized parabolic sheaves on curves are globally F-regular type.
