Nichtlineare Eigenwertprobleme mit zwei Parametern

In this paper we are searching for solutions (x,μdepending on (ε,τ)-of the nonlinear eigenvalue problem (A?λ)x+B(ε,x)+C(τ,x)=μx. Thus we are interested mainly in imposing such conditions on the analytic operators B(ε,x) and C(τ,x) that will ensure us to obtain solutions. Also we will discuss how these solutions depend onε andτ nearε=τ=0.
