Geometry and Materials Seminar

Blue Phases: Liquie Crystals With an Extra Twist
Gareth Alexander
2:00pm|S-101

The blue phases are remarkable mesophases appearing in highly chiral liquid crystals; they exhibit three-dimensional crystalline orientational order whilst remaining fully fluid. I will survey the development of our understanding of these materials...

Computer Science/Discrete Mathematics Seminar II

The Completeness of the Permanent
10:30am|S-101

In his seminal work, Valiant defined algebraic analogs for the classes P and NP, which are known today as VP and VNP. He also showed that the permanent is VNP-complete (that is, the permanent is in VNP and any problem in VNP is reducible to it). We...

Computer Science/Discrete Mathematics Seminar I

The Detectability Lemma and Quantum Gap Amplification
Itai Arad
11:15am|S-101

Constraint Satisfaction Problems appear everywhere. The study of their quantum analogues (in which the constraints no longer commute), has become a lively area of study, and various recent results provide interesting insights into quantum physics...

Short Talks by Postdoctoral Members

On Desingularization of Schemes
2:00pm|S-101

In this short talk I will formulate a functorial desingularization theorem for qe schemes of characteristic zero and explain why this result implies desingularization in other categories including formal schemes and analytic spaces. If time permits...
