Structure of Positive Solutions to a Semilinear Initial Value Problem

Funkcialaj Ekvacioj, 2003
Summary: We study an initial value problem for a semilinear ordinary differential equation. This problem is closely related to the blow-up behavior of a semilinear parabolic problem. under some restrictions, we characterize the structure of solutions and derive the uniqueness of positive global solutions of this initial value problem.

Existence of positive solutions to a nonlinear initial problem

Nonlinear Analysis: Theory, Methods & Applications, 2001
The authors prove the existence of a positive decreasing solution \(f=f(y)\) of the problem \(f''=yf'/2+f/(p-1)-f^p\) for \(y>0\), \(f'(0)=-f^{(p+1)/2}(0)\). This problem plays an important role in the study of the blow-up rate of blowing up solutions of the parabolic equation \(u_t=u_{xx}+u^p\) complemented by the nonlinear boundary condition \(u_\nu ...
