Abstract (Elsevier)
Introducing membranes as fundamental object in topological M-theory, we explore the global supersymmetry as well as the local κ -symmetry of the theory. Promoting the supersymmetry generators to be BRST operators, it is shown that the action can be chosen to be BRST exact. The presentation is given along the lines of [L. Bao, V. Bengtsson, M. Cederwall and B. E. W. Nilsson, JHEP 0601, 150 (2006) [ arXiv:hep-th/0507077 ]].
