We calculate the contribution of the tadpole for gauge field of the noncommutative gauge supersymmetric theory in two dimensions in Minkowski space. We have found two types of divergences UV/IR similar to those found in the contribution of the ghost field loop.
In a Robertson-Walker space-time, a spinning particle model is investigated. It is shown that in a stationary case a class of new structures called f-symbols exists ¢ Central European Science Journals. All rights reserved.
