Аннотация:The authors consider a Cauchy problem in RN, N≥1, as well as an initial-boundary value problem in a bounded domain Ω⊂RN with smooth boundary ∂Ω for a semilinear system of reaction-diffusion equations in the form
∂u/∂t=a2Δu−uv, ∂v/∂t=b2Δv−uv,(1)
where a and b are some constants. For nonnegative initial data u0, v0∈W2,p(RN)∩Lip(R¯¯¯N) and u0, v0∈C2+γ0(Ω¯¯¯), γ∈(0,1), the global existence of a unique classical solution for the Cauchy problem and for the initial-boundary value problem for (1), respectively, is proved, and Lp(RN) and Lp(Ω) estimates, respectively, for t large are obtained.
