Optimal double control problem for a PDE model of goodwill dynamics
Dominika Bogusz, Mariusz Górajski
We propose a new optimal model of product goodwill in a segmented market where the state variable is described by a partial differential equation of the Lotka--Sharp--McKendrick ty…
On the equivalence of solutions for a class of stochastic evolution equations in a Banach space
Mariusz Górajski
We study a class of stochastic evolution equations in a Banach space driven by cylindrical Wiener process. Three different concept of solutions: generalised strong, weak and mi…
Vector-valued stochastic delay equations - a weak solution and its Markovian representation
Mariusz Górajski
A class of stochastic delay equations in Banach space driven by cylindrical Wiener process is studied. We investigate two concepts of solutions: weak and generalised strong, an…
Vector-valued stochastic delay equations - a semigroup approach
Sonja Cox, Mariusz Górajski
Let E be a type 2 UMD Banach space, H a Hilbert space and let p be in [1,\infty). Consider the following stochastic delay equation in E: dX(t) = AX(t) + CX_t + b(X(t),X_t)dW_H(t),…
