DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MathMAC/54/"
 >Well posedness of the Euler system of gas dynamics</a>\nby Eduard Feireis
 l as part of Modelling of materials - theory\, model reduction and efficie
 nt numerical methods (UNCE MathMAC)\n\n\nAbstract\nWe discuss the well pos
 edness of the Euler system of gas dynamics from two different perpectives:
 \n1. Admissible solutions are inviscid limits of the Navier-Stokes-Fourier
  system.\n2. Admissible solutions comply with the maximum entropy producti
 on principle.\nWe show that these two criteria are in general not compatib
 le and give rise to different classes of solutions.\n\nThen we propose and
  admissibility criterion that gives rise to a unique solution semigroup of
  the Euler system in the class of generalized dissipative solutions. The s
 olutions are Borel measurable meaning ``almost'' continuous with respect t
 o the initial data.\n
