Positive Solutions Of A Third-Order Three-Point Boundary-Value Problem, Bo Yang Jul 2008

Positive Solutions Of A Third-Order Three-Point Boundary-Value Problem, Bo Yang

Faculty and Research Publications

We obtain upper and lower estimates for positive solutions of a third-order three-point boundary-value problem. Sufficient conditions for the existence and nonexistence of positive solutions for the problem are also obtained. Then to illustrate our results, we include an example.


Estimates Of Positive Solutions For Higher Order Right Focal Boundary Value Problem, Bo Yang Jan 2008

Estimates Of Positive Solutions For Higher Order Right Focal Boundary Value Problem, Bo Yang

Faculty and Research Publications

We consider the (p;n - p) right focal boundary value problem. A new set of upper and lower estimates of positive solutions for the boundary value problem are obtained. These estimates implement and improve the ones in the literature.
