SUMMARY:Seminar Analysis and Mathematical Physics: Stefano Spirito (Univers
 ità degli Studi dell'Aquila)
DESCRIPTION:I will review the existence and uniqueness theory of a model fo
 r viscoelastic materials of Kelvin-Voigt type with large strain. In partic
 ular\, I will first review the existence theory in L2\, and then show that
  also propagation of H1-regularity for the deformation gradient of weak so
 lutions in two and three dimensions holds.  Moreover\, in two dimensions
  it is also possible to prove uniqueness of weak solutions. Additional pro
 pagation of higher regularity can be obtained\, leading to a global in tim
 e existence of smooth solutions. Joint work with K. Koumatos (U. of Sussex
 )\, C. Lattanzio (UnivAQ) and A. Tzavaras (KAUST).
