Resumen

We consider the parabolic system u_t−aΔu=f(v),v_t−bΔv=g(u) in Ω×(0,T), where a,b>0, f,g:[0,∞)→[0,∞) are non-decreasing continuous functions and either Ω is a bounded domain with smooth boundary ∂Ω or the whole space R^N. We characterize the functions f and g so that the system has a local solution for every initial data (u₀,v₀)∈L^r(Ω)×L^s(Ω), u₀,v₀≥0, r,s∈[1,∞).
