Theoretical progress on H-mode physics

Theoretical research into H-mode physics is reviewed. The topics cover elementary processes such as bifurcation physics, collisional transport theory and anomalous transport theory. Associated with these investigations, a global picture of H-mode phenomena, such as the spatial structure and temporal evolution has been constructed from theory. The author tries to clarify the contributions of theoretical presentations in this H-mode workshop, illustrating the relation to the overall progress on the H-mode theory.
