Hamilton-Jacobi-Bellman Equation Arising from Optimal Portfolio Selection Problem
Daniel Sevcovic, Cyril Izuchukwu Udeani
The Hamilton-Jacobi-Bellman equation arising from the optimal portfolio selection problem is studied by means of the maximal monotone operator method. The existence and uniqueness…
Asymptotic limits of the principal spectrum point of a nonlocal dispersal cooperative system and application to a two-stage structured population model
Maria A. Onyido, Rachidi B. Salako, Markjoe O. Uba +1
This work examines the limits of the principal spectrum point, , of a nonlocal dispersal cooperative system with respect to the dispersal rates. In particular, we provide prec…
Linear and Nonlinear Partial Integro-Differential Equations arising from Finance
