Heat equation with dynamic boundary conditions
 Gregor, Michal ; Bárta, Tomáš (advisor) ; Průša, Vít (referee)
In this thesis we deal with the solution of the heat equation with a dynamic boundary condition, which relates the time derivative at the boundary and the normal flow at the boundary. We first deal with the derivation of this dynamic boundary condition and its physical interpretation. Furthermore, we solve problems in one spacial dimension, where we learn the necessary techniques, which we will then use in solving more complex two-dimensional problems on a square, an annulus and a circle. We proceed using the Fourier method. We convert the problem to finding eigenvalues and eigenfunctions of the Laplace operator, which satisfy a special boundary condition. We use the results from articles that say that such constructed eigenfunctions form a complete system in a suitable space of functions and so we are able to construct a general solution as their superposition.
