I will discuss the potential importance of a dark-sector phase
transition in the early universe in setting the measured relic
abundance, for a simple scenario with strongly interacting dark
matter. Enhancement of the dark matter density within...
The notion of Schmidt rank/strength for a collection of m
polynomials plays an important role in additive combinatorics,
number theory and commutative algebra; high rank collections of
polynomials are “psuedorandom”. An arbitrary collection
of...
First-passage percolation studies the geometry obtained from a
random perturbation of Euclidean geometry. In the discrete planar
setting, one assigns random, independent and identically
distributed, lengths to the edges of the lattice Z^2 and...
