Abstract
Let G be a Carnot group. We study nonlocal diffusion equations in a domain \(\Omega\) of G of the form
with \(u^\epsilon =g(x,t)\) for \(x\notin \Omega\). For an appropriated rescaled kernel \(K_\epsilon\), we apply the Taylor series development in Carnot groups in order to prove that the solutions \(u^\epsilon\) uniformly approximate the solution of a certain local Dirichlet problem in \(\Omega\), when \(\epsilon \rightarrow 0\).
