DESCRIPTION:Sir John Ball\nDirector of the Oxford Centre for Nonlinear Par
 tial Differential Equations\nWhen a new phase is nucleated in a martensiti
 c solid phase transformation\, it has to fit geometrically onto the parent
  phase\, forming interfaces between the phases accompanied by possibly com
 plex microstructure. The talk will describe some mathematical issues invol
 ved in understanding such questions of compatibility and their influence o
 n metastability\, as illustrated by recent experimental discoveries.\nFor 
 liquid crystals planar (as opposed to point and line) defects are not usua
 lly considered\, but there are some situations in which they seem to be re
 levant\, such as for smectic. A thin films where compatibility issues not 
 unlike those for martensitic materials arise.
