On the existence, uniqueness, and new analytic approximation of the
modifieded error function in two-phase Stefan problems
Abstract
The existence and uniqueness of the solution is proved for a nonlinear
boundary value problem for ODE subject to an infinite condition
\cite{1}, which describes the study of two-phase Stefan
problems on the semi-infinite line [0,\infty). This
result considerably extends the analysis of a recent work
\cite{4}. A highly accurate analytic approximate
solution of this problem is also provided via the Adomian decomposition
method.
