Konstantin Khanin coauthored a study connecting Feigenbaum constants with thermodynamic formalism, together with E. B. Vul and Yakov Sinai. This places the repeated scaling of period-doubling dynamics in a framework related to statistical mechanics, connecting detailed orbit geometry with collective scaling descriptions.^[ref]

Yakov Sinai contributed to the study of Feigenbaum constants through thermodynamic formalism, in joint work with E. B. Vul and Konstantin Khanin. Their 1984 paper connects universal period-doubling scaling with methods of statistical mechanics, illustrating how probabilistic and geometric descriptions of a dynamical system can reinforce each other.^[ref]
