Consider the solution of the free time-dependent Schr\"odinger equation withinitial data f. It is shown by Sj\"ogren and Sj\"olin (1989) that there existsf in the Sobolev space H^s(R^d), s=d/2 such that tangential convergence can notbe widened to convergence regions. In 2010 we obtained the correspondingresults for a generalized version of the Schr\"odinger equation, where-\Delta_x is replaced by an operator \phi(D), with special conditions on \phi.In this paper we show that similar results may be obtained for initial data inFourier Lebesgue spaces.
