Eighth Mississippi State - UAB Conference on Differential Equations and Computational Simulations. Electron. J. Diff. Eqns., Conference 19 (2010), pp. 135-149. Title: Population models with nonlinear boundary conditions Authors: Jerome Goddard II (Mississippi State Univ., MS, USA) Eun Kyoung Lee (Pusan National Univ., Busan, Korea) Ratnasingham Shivaji (Mississippi State Univ., MS, USA) Abstract: We study a two point boundary-value problem describing the steady states of a Logistic growth population model with diffusion and constant yield harvesting. In particular, we focus on a model when a certain nonlinear boundary condition is satisfied. Published September 25, 2010. Math Subject Classifications: 34B18, 34B08.
