Kislev developed a black hole metric within the quintessence field by analyzing the energy-momentum tensor, specifically using the condition $T^t_t=T^r_r$. The discussion revolves around whether there exists an action for the quintessence field that results in this energy-momentum tensor when varied with respect to the metric tensor $g^{\mu \nu}$. Participants are seeking a specific reference to Kislev's work for further examination. The inquiry highlights the relationship between quintessence and black hole metrics in theoretical physics. This exploration aims to deepen understanding of the implications of quintessence in cosmological models.

Kislev developed black hole metric in quintessence field by considering $T^t_t=T^r_r$ for energy momentum tesor corresponding to quintessence. Is there any action for the quintessence fild that gives such energy momentum tensor after varying with respect to $g^{\mu \nu}$?

Can you please cite the specific Kislev reference so we can take a look?

Theoretical physicist C.N. Yang died at the age of 103 years on October 18, 2025. He is the Yang in Yang-Mills theory, which he and his collaborators devised in 1953, which is a generic quantum field theory that is used by scientists to study amplitudes (i.e. vector probabilities) that are foundational in all Standard Model processes and most quantum gravity theories. He also won a Nobel prize in 1957 for his work on CP violation. (I didn't see the post in General Discussions at PF on his...
