Title: Some recent results on the Dirichlet problem for (p,q)-Laplace equations,
Abstract: A short account of recent existence and multiplicity theorems on the
Dirichlet problem for an elliptic equation with $(p,q)$-Laplacian in a bounded
domain is performed. Both eigenvalue problems and different types of
perturbation terms are briefly discussed. Special attention is paid to possibly
coercive, resonant, subcritical, critical, or asymmetric right-hand sides.
