In this paper, we consider a strongly-coupled parabolic system with initial boundary values. Under the appropriate conditions, using Gagliard-Nirenberg inequality, Poincaré inequality, Gronwall inequality and imbedding theorem, we obtain the global existence of solutions.
This paper deals with the blow-up rate estimates of positive solutions for systems of heat equationswith nonlinear boundary conditions. The upper and lower bounds of blow-up rate are obtained.
In this paper, the authors deal with the non-constant positive steady-states of a predator-prey-mutualist model with homogeneous Neumann boundary condition. They first give a priori estimates (positive upper and lower bounds) of positive steady-states,and then study the non-existence, the global existence and bifurcation of non-constant positive steady-states as some parameters are varied. Finally the asymptotic behavior of such solutions as d3 →∞ is discussed.
This paper deals with the blow-up rate estimates of solutions for semilinear parabolic systems coupled in an equation and a boundary condition. The upper and lower bounds of blow-up rates have been obtained.
This paper is devoted to study the classification of self-similar solutions to the m ≥ 1,p,q > 0 and p + q > m. For m = 1, it is shown that the very singular self-similar solution exists if and only if nq + (n + 1)p < n + 2, and in case of existence, such solution is unique. For m > 1, it is shown that very singular self-similar solutions exist if and only if 1 < m < 2 and nq + (n + 1)p < 2 + mn, and such solutions have compact support if they exist. Moreover, the interface relation is obtained.
