Starting from just a sheet of paper, by folding, stacking, crumpling, tearing, we will explore a rich variety of phenomena, from magic tricks and geometry to elasticity and the traditional Japanese art of origami. Much of the lecture consists of actual table-top demos, which you can try later with friends and family.

I am interested in the following problem: "classify all smooth connected D-affine projective varieties".
As a part of their proof of Kazhdan-Lusztig Conjecture, Beilinson and Bernstein have proved that
the partial flag varieties G/P are D-affine. This is the current state of art: no other examples are known
but there is no proof that the G/P-s exhaust all the possible examples.

In my talk I will show that in three natural classes of varieties D-affinity implies that the variety is G/P,

Motivated by metaplectic invariants of Goldschmidt–Jones,
generalizing the cyclotomic invariants of Kobayashi–Murakami–Murakami,
I will explain a construction which associates to each oriented link
diagram a symmetric matrix with elements being quadratic polynomials
in one indeterminate with integer coefficients. Based on a slightly
modified S-equivalence of Trotter and Murasugi in the space of
symmetric matrices, the construction gives rise to an invariant
of oriented links. In particular, the signature of the matrix is

In this talk, I will define the classical and non-classical of the wave equation.
Also, I will give some motivations about why low regularity scenarios are interesting.
Finally, I will focus on the classical ones and its relationship with  Quantum Field Theory in spacetimes with limited regularity.
