Abstract

A computation of the Casimir effect for a real scalar field in four situations: on a segment of a line, on a circle and on both standard commutative and noncommutative two-spheres is presented. The main aim of this paper is to discuss the Casimir energy on a noncommutative sphere within the theory with commutative time. A discussion of the (non)commutative cylinder is also given.

Keywords

Casimir effect; real scalar field; segment of a line; circle; commutative and noncommutative two-spheres; (non)commutative cylinder
