We consider the nonlinear two parameter eigenvalue problem (Tp − λ1Ap1 − λ2Ap2 − λ1λ2Ap3)vp = 0, where λ1, λ2 ∈C; Tp, Apk (p = 1, 2;k = 1, 2, 3) are matrices. Bounds for the spectral radius of that problem are suggested. Our main tool is the recent norm estimates for the resolvent of an operator on the tensor product of Euclidean spaces. In addition, we investigate perturbations of the considered problem and derive a Gershgorin type bounds for the spectrum. It is shown that the main result of the paper is sharp.
