This is intended to be a survey talk, accessible to a general mathematical audience. The cdh topology was created by Voevodsky to extend motivic cohomology from smooth varieties to singular varieties, assuming resolution of singularities (for...

We use critical block sensitivity, a new complexity measure introduced by Huynh and Nordstrom (STOC 2012) to study the communication complexity of search problems. Our main result is a simple proof that if \(S\) is a search problem with high...

Grothendieck has proposed, under the name of "motives" a kind of Galois theory for non algebraic numbers. A mystery of the so-called "standard model" in high energy physics is the occurrence of about twenty numerical constants, independent of the...

The Milnor fibre of any isolated hypersurface singularity contains exact Lagrangian spheres: the vanishing cycles associated to a Morsification of the singularity. Moreover, for simple singularities, it is known that the only possible exact...

We prove a B-SD conjecture for elliptic curves (for the \(p^\infty\) Selmer groups with arbitrary rank) a la Mazur-Tate and Darmon in anti-cyclotomic setting, for certain primes \(p\). This is done, among other things, by proving a conjecture of...

Block models are random graph models which have been extensively studied in statistics and theoretical computer science as models of communities and clustering. A conjecture from statistical physics by Decelle et. al predicts an exact formula for...
