Description:: We give sufficient conditions ensuring that any positive classical solution (u,v) of an elliptic system in the whole n-dimensional space has the symmetry property u=v. As an application, we improve some known results on Sobolev-critical elliptic systems of Schrodinger type. Our techniques apply to some supercritical problems as well. We also obt...

Description:: Keywords: Low Reynolds number; locomotion; symmetry-breaking; synchronization; cilia; optimizationAbstract: Fluid mechanics plays a crucial role in many cellular processes. One example is the external fluid mechanics of motile cells such as bacteria, spermatozoa, algae, and essentially half of the microorganisms on earth. The most commonly-studi...

Description:: In this talk I will discuss qualitative properties of global minimizers of the Ginzburg-Landau energy which describes light-matter interaction in the theory of nematic liquid crystals near the Friedrichs transition. This model depends on two parameters: É›>0 which is small and represents the coherence scale of the system and aâ‰§ 0 which represe...

Description:: By the 'realistic biometric context' of my title, I mean an investigation of well-calibrated images from a moderately large sample of organisms in order to evaluate some nontrivial hypothesis about systematic form-factors (e.g., a group difference). One common approach to such problems today is 'geometric morphometrics,' a short namefor the mult...

Description:: Motivated by the problem of symmetric collapsing gas-dynamical shocks wepresent a scalar toy model that captures blowup of focusing waves. This modelis simple enough to allow for explicit calculations, and we study some solutions indetail. As a scalar model it does not describe reflection of waves and this necessitatesa new concept of weak solut...
