Laplacian path models

Journal d'Analyse Mathématique, 2002
This paper deals with the following growth model; let \(\{K_t\}\), \(t\geq t_0\), be a growing family of connecting sets, where \(K_{t_0}\) is the initial configuration, and \(K_s\subset K_t\) for \(s< t\). The growth is localized at a finite number of points \(a_j(t)\), \(1\leq j\leq d\), so that \(K_t\setminus K_{t_0}\) consists of \(d\) disjoint ...

Laplacians and Sub-Laplacians

2010
We have seen in the previous chapters how an elliptic operator can be associated in a natural way with a geometric Riemannian structure. In a similar way sub-elliptic operators arise from similar structures, called sub-Riemannian structures, which will be discussed next. References for sub-Riemannian manifolds are [27] and [92].
