Abstract

We study the dynamics of the critical collapse of a spherically symmetric scalar field. Approximate analytic expressions for the metric functions and matter field in the large-radius region are obtained. In the central region, owing to the boundary conditions, the equation of motion for the scalar field is reduced to the flat-spacetime form.

临界坍塌动力学新成果* * JQG 由山东省自然科学基金资助（ZR2019MA068）。YH、PPW 和 CGS 受国家自然科学基金资助（11925503）

我们研究了球对称标量场临界坍缩的动力学。我们得到了大半径区域的度量函数和物质场的近似解析表达式。在中心区域，由于边界条件，标量场的运动方程被简化为平时空形式。
