Cutoff for generalised Bernoulli-Laplace urn models

Ritesh Goenka, Jonathan Hermon, Dominik Schmid

We introduce a multi-colour multi-urn generalisation of the Bernoulli-Laplace urn model, consisting of $d$ urns, $m$ colours, and $d mn$ balls, with $d n$ balls of each colour and $m…

On subsets of lattice cubes avoiding affine and spherical degeneracies

Anubhab Ghosal, Ritesh Goenka, Peter Keevash

For integers $1 < k < d - 1$ and $r \geq k + 2$ , we establish new lower bounds on the maximum number of points in $[n]^{d}$ such that no $r$ lie in a $k$ -dimensional affine (or linear) su…

The maximum number of triangles in $K_{1, s, t}$ -free graphs

Asier Calbet, Ritesh Goenka

We consider the following generalized Turán problem: For $2 \leq s \leq t$ , what is the maximum number of triangles in a $K_{1, s, t}$ -free graph on $n$ vertices? The previously best k…
