  abstract = {The nonlinear Dirichlet problem is considered for maps from a two
	dimensional domain into trees with one branch point. The Dirichlet
	energy is defined using a semigroup approach based on Markov kernels.
	The problem is discretized using a suitable finite element approach
	and convergence of a corresponding iterative numerical method is
	proved. The presented approach integrates stochastic methods on discrete
	lattices and finite element projection techniques. Finally, a couple
	of numerical results are presented.},
