Corrections to Hermitian Morita equivalences between maximal orders in central simple algebras

Abstract

Corrections to Dasgupta’s “Hermitian Morita equivalences between maximal orders in central simple algebras” (Illinois J. Math. 53 (2009) 723–736) follow. $\operatorname{char} K=2$ was not considered in the paper, nor was the fact that $\delta^{-1}y_1^\beta y_1^{-1}\epsilon$ could be equal to $-1$ at a couple of points in the proof of Proposition 3 of the paper. Changes in the proof of Proposition 3, in its statement and the corresponding changes in the statements of Theorems 1, 2 and 3 follow.
