Polytopality criteria for the mix of polytopes and maniplexes
The mix of two maniplexes is the minimal maniplex that covers both. This construction has many important applications, such as finding the smallest regular cover of a maniplex. If one of the maniplexes is an abstract polytope, a natural question to ask is whether the mix is also a polytope. We describe here a general criterion for the polytopality of the mix which generalizes several previously-known polytopality criteria.

Correlator Polytopes
Recently, "cosmohedra" have been introduced as polytopes underlying the cosmological wavefunction for conformally coupled Tr($Φ^3$) theory in FRW cosmologies, generalizing associahedra for flat space scattering amplitudes. In this letter we show that correlation functions are also directly captured by a new polytope - the "Correlatron". The combinatorics of correlation functions is an interesting blend of flat space scattering amplitudes and wavefunctions. This is reflected in the correlatron …

Tech industry group sues Arkansas over new social media laws
A tech industry trade group has sued Arkansas over two new law placing limits on content on social media platforms. The lawsuit was filed Friday in federal court by NetChoice, whose members include TikTok, Facebook parent Meta, and X, formerly known as Twitter. The lawsuit comes months after a federal judge struck down an Arkansas law that would have required parental consent for minors to create new social media accounts. The new laws the group is challenging include one that would allow paren…
