一个小黑洞的非对易模型

A non commutative model for a mini black hole

Ivan Arraut Guerrero, Davide Batic, Marek Nowakowski

摘要:

我们分析了受非对易几何启发的爱因斯坦场方程的静态和球对称理想流体解。在非对易几何的框架下,这个解被解释为一个在事件视界外具有史瓦西几何的迷你黑洞,但其标准中心奇点被自引力液滴所取代。液滴的能量动量张量是各向异性流体服从非局部状态方程的能量动量张量。液滴的半径是有限的,而引起流体静力平衡的压力在内部是正定的。

英文摘要:

We analyze the static and spherically symmetric perfect fluid solutions of Einstein field equations inspired by the non commutative geometry. In the framework of the non commutative geometry this solution is interpreted as a mini black hole which has the Schwarzschild geometry outside the event horizon, but whose standard central singularity is replaced by a self-gravitating droplet. The energy-momentum tensor of the droplet is of the anisotropic fluid obeying a nonlocal equation of state. The radius of the droplet is finite and the pressure, which gives rise to the hydrostatic equilibrium, is positive definite in the interior.
