A Skew Stochastic Heat Equation [PDF]

open access: yesJournal of Theoretical Probability, 2012
We consider a stochastic heat equation driven by a space-time white noise and with a singular drift, where a local-time in space appears. The process we study has an explicit invariant measure of Gibbs type, with a non-convex potential. We obtain existence of a Markov solution, which is associated with an explicit Dirichlet form.

Conductive Heat Transfer in Thermal Bridges

open access: yesEncyclopedia, 2022
A thermal bridge is a component of a building that is characterized by a higher thermal loss compared with its surroundings. Their accurate modeling is a key step in energy performance analysis due to the increased awareness of the importance of ...

A Variational Quantum Linear Solver Application to Discrete Finite-Element Methods

open access: yesEntropy, 2023
Finite-element methods are industry standards for finding numerical solutions to partial differential equations. However, the application scale remains pivotal to the practical use of these methods, even for modern-day supercomputers.

Inflation driven by causal heat flux [PDF]

open access: yes, 1997
We find a simple inflationary solution in an inhomogeneous spacetime with heat flux. The heat flux obeys a causal transport equation, and counteracts the inflationary decrease of energy density.

MULTI-TERM TIME-FRACTIONAL DERIVATIVE HEAT EQUATION FOR ONE-DIMENSIONAL DUNKL OPERATOR

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2022
In this paper, we investigate the well-posedness for Cauchy problem for multi-term time-fractional heat equation associated with Dunkl operator. The equation under consideration includes a linear combination of Caputo derivatives in time with decreasing ...

Probabilistic representations of solutions to the heat equation [PDF]

open access: yes, 2003
In this paper we provide a new (probabilistic) proof of a classical result in partial differential equations, viz. if $\phi$ is a tempered distribution, then the solution of the heat equation for the Laplacian, with initial condition $\phi$, is given by ...

On a time-optimal control problem for a heat conduction equation with involution [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
In this paper, we consider a boundary control problem for a heat conduction equation with involution in a bounded one-dimensional domain. The solution with the control function on the border of the rod is given.
