Can primordial wormholes be induced by GUTs at the early Universe?
S. Nojiri, O. Obregon, S. D. Odintsov +1
Using large N, 4d anomaly induced one-loop effective action for conformally invariant matter (typical GUT multiplet) we study the possibility to induce the primordial spherically s…

(Non) singular Kantowski-Sachs Universe from quantum spherically reduced matter
S. Nojiri, O. Obregon, S. D. Odintsov +1
Using s-wave and large N approximation the one-loop effective action for 2d dilaton coupled scalars and spinors which are obtained by spherical reduction of 4d minimal matter is fo…

Induced wormholes due to quantum effects of spherically reduced matter in large N approximation
S. Nojiri, O. Obregon, S. D. Odintsov +1
Using one-loop effective action in large N and s-wave approximation we discuss the possibility to induce primordial wormholes at the early Universe. An analytical solution is found…
