  In this paper, we analyze an eigenvalue problem for a quasi-linear elliptic
operators involving Dirichlet boundary condition in an open smooth bounded set
of $\mathbb{R}^N$. We investigate a bifurcation results (from trivial solution
and from infinity) of an eigenvalue problem involving the $(p,2)$-Laplace
operator, from the Fu\v cik spectrum of the Laplacian.
