Isomonodromic deformations in genus zero and one: algebrogeometric   solutions and Schlesinger transformations
  Here we review some recent developments in the theory of isomonodromic deformations on Riemann sphere and elliptic curve. For both cases we show how to derive   Schlesinger transformations together with their action on tau-function, and construct classes of solutions in terms of multi-dimensional theta-functions.
