The Heat Equation on Discrete Domains

In this paper, we will explore the properties of the Heat Equation on Discrete Networks, laying out groundwork and giving general forms for solutions, and then exploring the inverse problem. We will also focus on comparisons of Heat Networks with Electrical and Random-Walk Networks.

Discrete Scale Spaces via Heat Equation

Scale spaces allow us to organize, compare and analyse differently sized structures of an object. The linear scale space of a monochromatic image is the solution of the heat equation using that image as an initial condition. Alternatively, this linear scale space can also be obtained applying Gaussian filters of increasing variances to the original image. In this work, we compare (by looking at...

Controllability of the time discrete heat equation

Abstract. In this paper we study the controllability of an Euler Implicit time discrete heat equation in a bounded domain with a local internal controller. We prove that, based on Lebeau-Robbiano’s time iteration method, the projection in appropriate filtered space is null controllable with uniformly bounded control. In this way, the well-known null-controllability property of the heat equation...

On the Discrete Heat Equation Taking Values on a Tree

The basic ideas about differential equations taking values on manifolds are well known. Usually one localizes to a coordinate patch, and studies the differential equation using local coordinates. If the manifold structure is smooth, then this procedure yields a new differential equation on Euclidean space, and one can use existing theory. However, there are two cases which may cause trouble: th...

Strong convergence of discrete DG solutions of the heat equation

A convergence analysis to the weak solution is derived for interior penalty discontinuous Galerkin methods applied to the heat equation in two and three dimensions under general mixed boundary conditions. Strong convergence is established in the DG norm, as well as in the L norm, in space and in the L norm in time.
