SUMMARY:Geometric compatibility\, quasiconvexity and phase transitions - K
 onstantinos Koumatos (Oxford)

DESCRIPTION:Remarkable experimental observations of H. Seiner\, in which a
 ustenite is nucleated in martensite by localized heating in a CuAlNi singl
 e crystal\, clearly demonstrate the important role of geometric compatibil
 ity between phases in the nucleation process. This talk proposes an explan
 ation for the experimental observations in terms of quasiconvexity conditi
 ons in the interior and the boundary of a bar-shaped domain. This is joint
  work with John Ball.
