Dynamic portfolio choice problems with non-monotone utility functions
Portfolio monotone Mean-variance preferences, Continuous-Time
2010/9/13
In this paper, based on a non-monotone utility function being revised to a monotone utility function, we study the multi-period and continuous-time optimal consumption-investment choice model, and giv...
Positive Steady States of A Prey-predator Model with Diffusion and Non-monotone Conversion Rate
A prey--predator model Steady states Existence Uniqueness Stability
2007/12/11
In this paper, we study the positive steady states of a prey--predator model with diffusion throughout and a non-monotone conversion rate under the homogeneous Dirichlet boundary condition. We obtain ...
