Resumen de Condensation phenomena in nonlinear drift equations

José Carrillo Menéndez , Marco Di Francesco, Giuseppe Toscani

• We study non-negative, measure-valued solutions to nonlinear drifttype equations modelling concentration phenomena related to Bose-Einstein particles.

  In one spatial dimension, we prove existence and uniqueness for measure solutions. Moreover, we prove that all solutions blow up in finite time leading to a concentration of mass only at the origin, and the concentrated mass absorbs increasingly the mass converging to the total mass as t → ∞. Our analysis makes a substantial use of independent variable scalings and pseudo-inverse functions techniques.
