Is there a problem with quantum wormhole states in N= 1
... Quite recently, some important results were achieved [8,9]. On the one hand, addressing the question of why the existence of a Hartle-Hawking [10] solution for Bianchi class A models in pure N=1 supergravity [11-15] seemed to depend on the homogeneity condition for the gravitino [13]. In fact, it do ...
