On extension of CR functions from piecewise smooth manifolds into a wedge
A stronger version of the well known theorem of Airapetyan-Henkin concerning the analytic extendability of CR functions from piecewise smooth manifolds into a wedge is proved in this very interesting paper. Moreover, estimates on the size of the wedge of extendability are given by means of the size of the second derivatives of the functions defining the manifolds in question.
