The indefinite metric of R. Mrugala and the geometry of the thermodynamical phase space
We study the indefinite metric $G$ in the contact phase space $(P,\theta)$ of a homogeneous thermodynamical system introduced by R. Mrugala. We calculate the curvature tensor, Killing vector fields, second fundamental form of Legendre submanifolds of $P$

Geometry of Weak Metric f-Manifolds: A Survey
The interest of geometers in f-structures is motivated by the study of the dynamics of contact foliations, as well as their applications in physics. A weak f-structure on a smooth manifold, introduced by the author and R. Wolak, generalizes K.

Quantization of Midisuperspace Models
We give a comprehensive review of the quantization of midisuperspace models. Though the main focus of the paper is on quantum aspects, we also provide an introduction to several classical points related to the definition of these models.

Reconstructing Isometry Groups From Killing Vector Fields
Abstract This work aims to explore a novel relation between Killing vector fields and Lie algebras using induced vector fields. On one hand, Killing vector fields on a (pseudo) Riemannian manifold are related to directions of local isometries along it.
