The peculiar properties of block copolyme rs is their self-assembly property\, that leads to the creation of fascina ting patterns exhibiting interesting periodicity properties. The pattern d etermines the physical properties of the compound\, and it is therefore of great interest to being able to understand the mechanism behind this patt ern formation. It has been seen in experiments that when block copolymers are constrained in thin films\, interfacial forces are dominant with respe ct to bulk forces\, and therefore the landscape of patterns can be very di fferent from that of block copolymers in bulk.\n\nIn this talk we consider a model\, inspired by one derived by Choksi and Ren\, to understand patte rn formation of diblock copolymers in thin films. We will discuss the rela xed energy and partial regularity of mass constrained minimizers in two sp atial dimensions.\n\nThis talk is based on a joint work with Marco Bonacin i (Università di Trento).\n LOCATION:https://researchseminars.org/talk/VCU_ALPS/18/ END:VEVENT END:VCALENDAR
