Abstract: | We propose a novel approach to modeling advertising dynamics for a firm operating over a distributed market domain based on
controlled partial differential equations of the diffusion type. Using our model, we consider a general type of finite-horizon
profit maximization problem in a monopoly setting. By reformulating this profit maximization problem as an optimal control
problem in infinite dimensions, we derive sufficient conditions for the existence of its optimal solutions under general profit
functions, as well as state and control constraints, and provide a general characterization of the optimal solutions. Sharper,
feedback-form characterizations of the optimal solutions are obtained for two variants of the general problem.
