This paper is devoted to the study of the behaviors of the solution to Fujita-type equations on finite graphs. Under certain conditions given by absorption term of the equations, we prove respectively local existence and blow-up results of solutions to Fujita-type equations on finite graphs. Our results contain some previous results as special cases. Finally, we provide some numerical experiments to illustrate the applicability of the obtained results. [ABSTRACT FROM AUTHOR]

In this paper, we establish several results involving the minimum and maximum principles and the comparison principles for elliptic equations and parabolic equations on finite graphs. The results are then used to prove the monotonicity and asymptotic properties of solutions for parabolic equations whose initial values are given by the equation Δ ψ + f (ψ) = 0 with Dirichlet boundary conditions. Finally, an illustration with numerical experiments is provided to demonstrate our main results. [ABSTRACT FROM AUTHOR]
