Extended VC-dimension, and Radon and Tverberg type theorems for unions of convex sets
We define and study an extension of the notion of the VC-dimension of a hypergraph and apply it to establish a Tverberg type theorem for unions of convex sets. We also prove a new Radon type theorem for unions of convex sets, vastly improving the estimates in an earlier result of Bárány and Kalai.

No-dimensional Tverberg-type problems
Recently, Adiprasito et al. have initiated the study of the so-called no-dimensional Tverberg problem. This problem can be informally stated as follows: Given $n\geq k$, partition an $n$-point set in Euclidean space into $k$ parts such that their convex hulls intersect a ball of relatively small radius. In this survey, we aim to present the recent progress towards solving the no-dimensional Tverberg problem and new open questions arising in its context. Also, we discuss the colorful variation…

Behavioural surplus is the extra information that can be processed when we interact with an app, website or device, in order to be repackaged and sold as accurate predictions about us.

If groups of parents can band together when deciding on the right age for a smartphone for their younger children, they will stand a better chance to avoid making decisions based on peer pressure at school.
