Introduction and Notations Cauchy-Dirichlet problem for general Schrodinger systems in domains containing conical points has been investigated in 1 2 . Cauchy-Neumann problems have been dealt with for hyperbolic systems in 3 and for parabolic equations in 4-6 . In this paper we consider the Cauchy-Neumann problem for the second-order general Schrodinger equations in infinite cylinders with nonsmooth bases. The solvability of this problem has been considered in 7 . Our main purpose here is to study the regularity of weak solution of the mentioned problem. The paper consists of six sections. In Section 1 we introduce some notations and functional spaces used throughout the text. A weak solution of the problem is defined in Section 2 together with some results of its unique existence and smoothness with the time variable. Our main result the regularity with respect to both of time and spatial variables of
