Cosmological Dynamics and Observational Constraints of a Logarithmic Herglotz $f(R,T)$ Gravity

We investigate the cosmological dynamics and observational viability of a logarithmic Herglotz-type $f(R,T)$ gravity model described by $f(R,T)=R+\beta\ln(-T/T_0)$. Assuming a spatially flat Friedmann--Lema\^{i}tre--Robertson--Walker background and pressureless matter, the modified field equations are formulated as a c...

Observational viability of Herglotz $f(R,T)$ gravity: A multi-probe Bayesian analysis

We investigate the observational viability of the linear Herglotz-type $f(R,T)$ gravity model, $f(R,T)=R+\alpha T$, which incorporates both geometry--matter coupling and non-conservative gravitational dynamics. Unlike previous analyses\cite{Wazny:2025jth} based on illustrative parameter choices, we perform a systematic...
