Geothermal space heating [PDF]
Geothermics, 2003 The use of geothermal resources for space heating dominates the direct use industry, with approximately 37% of all direct use development. Of this, 75% is provided by district heating systems. In fact, the earliest known commercial use of geothermal energy was in Chaudes-Aigues Cantal, France, where a district heating system was built in the 14th ...

Heat Flow on Alexandrov Spaces [PDF]
Communications on Pure and Applied Mathematics, 2012 AbstractWe prove that on compact Alexandrov spaces with curvature bounded below the gradient flow of the Dirichlet energy in the \documentclass{article} \usepackage{mathrsfs} \usepackage{amsmath, amssymb} \pagestyle{empty} \begin{document} \begin{align*}L^2\end{align*} \end{document}‐space produces the same evolution as the gradient flow of the ...

The Heat Kernel on Hyperbolic Space [PDF]
Bulletin of the London Mathematical Society, 1998 A new proof of the explicit formula for the heat kernel on hyperbolic space is provided. This formula is due to \textit{H. P. McKean} [J. Differ. Geom. 4, 359-366 (1970; Zbl 0197.18003)] for the case of the two-dimensional hyperbolic space and to \textit{A. Debiard, B. Gaveau} and \textit{E. Mazet} [Publ. Res. Inst. Math. Sci., Kyoto Univ. 12, 391-425 (

Climate justice: air quality and transitions from solid fuel heating
Buildings & Cities, 2020 Of all the European Union’s member states, Poland has the most acute ambient air pollution problem. An urgent transition from solid-fuel heating ('e.g.' coal and wood) in the housing sector is required to improve air quality in the country.

The Heat Semigroup on Configuration Spaces
Publications of the Research Institute for Mathematical Sciences, 2003 In this paper, we study properties of the heat semigroup of configuration space analysis. Using a natural “Riemannian-like” structure of the configuration space Γ_X over a complete, connected, oriented, and stochastically complete Riemannian ...
