Journal of Inequalities and Applications volume 2008, Article number: 310924 (2008)
Abstract
The boundary value problem 
, 
, 
, 
, and 
is strictly decreasing on 
, is considered. Here, 
are constants having the following properties: 
are strictly positive and 
. Necessary or sufficient conditions are given in terms of 
for the existence of concave solutions of the above nonlinear boundary value problem (NLBVP). Numerical illustration is given. This kind of results is useful in the experiment planning and technology design of single crystal rod growth from the melt by edge-defined film-fed growth (EFG) method. With this aim, this study was undertaken.
