Abstract

In this paper the present status of theoretical understanding - mostly relying on mean-field dynamo models - of global magnetic activity of late-type stars with convective envelopes is reviewed. The principles of the mean-field dynamo theory are introduced, and a discussion on some of the present-day problems and challenges is presented. The remaining sections are devoted to discuss the current status of solar and stellar dynamo models.
