Abstract
We address past and future trends in the theory and modeling of galactic cosmic rays in the heliosphere, and select some of the outstanding issues where future progress is anticipated. We discuss the theory of diffusive transport, briefly discuss drifts, the force-field approximation, and current numerical methods. Special attention is given to the areas of modeling cosmic rays in the heliosheath, the implications of the recent unusual solar minimum, and the understanding of high rigidity cosmic-ray anisotropies.
