引入了比现有文献更一般的边界条件,这些条件在f(R)引力中产生了适定的驻定作用量原理。这些条件涵盖了已知情形,从而扩大了可容许解的空间。相应的Gibbons-Hawking-York边界项被显式计算,并适用于任何解析的f(R)。在结论中概述了关于标量-张量映射和黑洞热力学定律的应用前景。
英文摘要
More general boundary conditions are introduced - with respect to known literature - which produce a well-posed stationary action principle in $f(R)$ gravity. These conditions encompass the known cases, thus enlarging the space of admissible solutions. The corresponding Gibbons-Hawking-York boundary terms are explicitly computed and hold for any analytic f(R). The perspectives of application concerning the scalar-tensor mapping and the laws of black-hole thermodynamics are outlined in the conclusions.
