  The aim of the present work is to derive a error estimates for the Laplace
eigenvalue problem in mixed form, by means of a virtual element method. With
the aid of the theory for non-compact operators, we prove that the proposed
method is spurious free and convergent. We prove optimal order error estimates
for the eigenvalues and eigenfunctions. Finally, we report numerical tests to
confirm the theoretical results together with a rigorous computational analysis
of the effects of the stabilization in the computation of the spectrum.
