The quantum field theory on the universe model of closed Friedmann,i.e.the third quantization,is discussed in detail,and an abnormal distribution is given which is different from Hosoya’s result.
In this paper,we discuss the wormhole with the topology of R^(1)×S^(3)×T^(d) in higher order gravitational theory with αR^(2)+βR _(μν)R^(μν) term,and derive corresponding worm hole equations as well as...In this paper,we discuss the wormhole with the topology of R^(1)×S^(3)×T^(d) in higher order gravitational theory with αR^(2)+βR _(μν)R^(μν) term,and derive corresponding worm hole equations as well as their analytical solution.展开更多
