In the original CPT theorem one is restricted to flat space and
is unable to make converse statements. In this talk I will show how
we can reformulate the CPT theorem using a symmetry argument and
generalise it to beyond flat space. This in turn...
The Milky Way contains of order 10^8 stellar-mass black holes
(BHs). Yet, fewer than 100 BH candidates are known, and only about
20 are dynamically confirmed. Our view of the BH population has
been shaped almost entirely by observations of X-ray...
Let π be a cuspidal automorphic representation of Sp_2n over Q
which is holomorphic discrete series at infinity, and χ a Dirichlet
character. Then one can attach to π an orthogonal p-adic Galois
representation ρ of dimension 2n+1. Assume ρ is...
Endow the edges of the ZD lattice with positive weights, sampled
independently from a suitable distribution (e.g., uniformly
distributed on [a,b] for some b greater than a greater than 0). We
wish to study the geometric properties of the resulting...
p-adic heights have been a rich source of explicit functions
vanishing on rational points on a curve. In this talk, we will
outline a new construction of canonical p-adic heights on abelian
varieties from p-adic adelic metrics, using p-adic Arakelov...
Any non-negative univariate polynomial over the reals can be
written as a sum of squares. This gives a simple-to-verify
certificate of non-negativity of the polynomial. Rooted in
Hilbert's 17th problem, there's now more than a century's work
that...
We discuss the shape invariant, a sort of set valued symplectic
capacity defined by the Lagrangian tori inside a domain of R4.
Partial computations for convex toric domains are sometimes enough
to give sharp obstructions to symplectic embeddings...
In distributed certification, our goal is to certify that a
network has a certain desired property, e.g., the network is
connected, or the internal states of its nodes encode a valid
spanning tree of the network. To this end, a prover
generates...
I'll give an exposition of the theory of "multiplicative
polynomial laws," introduced by Roby, and how (following a
suggestion of Scholze) they can be applied to the theory of
commutative (flat) group schemes. This talk will feature more
questions...
