L2-Estimates for a class of pseudo-differential operators defined on the torus

Abstract. In this work we establish L2 estimates from pseudo-differential operators defined on the torus. Such operators arise from the study of operators on locally compact abelian groups.
Keywords: Pseudo-differential operators, L2-boundedness, locally compact groups.
