Poincaré Inequalities for Mutually Singular Measures

Analysis and Geometry in Metric Spaces, 2015
Using an inverse system of metric graphs as in [3], we provide a simple example of a metric space X that admits Poincaré inequalities for a continuum of mutually singular measures.

Some New Fixed Point Theorems in Partial Metric Spaces with Applications

Journal of Function Spaces, 2017
Recently, a number of fixed point theorems for contraction type mappings in partial metric spaces have been obtained by various authors. Most of these theorems can be obtained from the corresponding results in metric spaces.

Cost–Benefit Analysis for Flexibility in Hydrothermal Power Systems

Energies
The world is experiencing an energy transition, migrating from fossil fuels to renewables, which are usually intermittent and, therefore, require flexibility to keep the power system reliable. Although system flexibility is a well-known theme of research,

Duality equations on a 4-manifold of conformal torsion-free connection and some of their solutions for the zero signature

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
On a 4-manifold of conformal torsion-free connection with zero signature (--++) we found conditions under which the conformal curvature matrix is dual (self-dual or anti-self-dual).
