      On the metric graph model for flows in tubular nanostructures 

      Smolkina, M.O.; Popov, I.Y.; Blinova, I.V.; Milakis, Emmanouil (2019)
      A metric graph model is suggested for the Stokes flow concentrated in the vicinity of a network embedded in R3. As a basic problem, we consider the case corresponding to strong variation of the viscosity and density in a ...

      On the regularity of the non-dynamic parabolic fractional obstacle problem 

      Athanasopoulos, Ioannis; Caffarelli, Luis; Milakis, Emmanouil (2018)
      In the class of the non-dynamic Fractional Obstacle Problems of parabolic type, it is shown existence, uniqueness, apriori bounds of the solution and optimal regularity of the space derivatives of the solution. Furthermore, ...

      Parabolic Obstacle Problems. Quasi-convexity and Regularity 

      Athanasopoulos, Ioannis; Caffarelli, Luis; Milakis, Emmanouil (2019)
      In a wide class of the so called Obstacle Problems of parabolic type it is shown how to improve the optimal regularity of the solution and as a consequence how to obtain space-time regularity of the corresponding free boundary.

      Regularity for Fully Nonlinear Parabolic Equations with Oblique Boundary Data 

      Chatzigeorgiou, Georgiana; Milakis, Emmanouil (2019)
      We obtain up to a flat boundary regularity results in parabolic Hölder spaces for viscosity solutions of fully nonlinear parabolic equations with oblique boundary conditions.
