标题： Evolution of thin-wall configurations of texture matter

摘要： 我们考虑了广义相对论中完美流体近似下的整体纹理自由物质问题。 我们将纹理物质的热力学性质与辐射流体和气泡物质进行了比较。 然后我们研究了薄壁自引力纹理物体的动力学，并表明经典运动可以是椭圆的（有限的）、抛物线的或双曲线的。 结果表明，处于平衡状态的中性纹理的总引力质量为零，这与预期一致。 最后，我们在考虑空间拓扑的情况下，对该理论进行了惠勒-德威特的最小超空间量子化，得到了精确的波函数和束缚态的离散能谱。 显示英文摘要

摘要： We consider the free matter of global textures within the framework of the perfect fluid approximation in general relativity. We examine thermodynamical properties of texture matter in comparison with radiation fluid and bubble matter. Then we study dynamics of thin-wall selfgravitating texture objects, and show that classical motion can be elliptical (finite), parabolical or hyperbolical. It is shown that total gravitational mass of neutral textures in equilibrium equals to zero as was expected. Finally, we perform the Wheeler-DeWitt's minisuperspace quantization of the theory, obtain exact wave functions and discrete spectra of bound states with provision for spatial topology.
