$A_{3}$ -formality for pro-2 Demushkin groups

Ambrus PÃ¡l, Ambrus Pál, Gereon Quick

We study a weak form of formality for differential graded algebras, called $A_{3}$ -formality, and show that the differential graded $F_{2}$ -algebras of continuous cochains of…

The minimal width of universal $p$ -adic ReLU neural networks

SÃ¡ndor Z. Kiss, Ambrus PÃ¡l

We determine the minimal width of $p$ -adic neural networks with the universal approximation property for continuous $Q_{p}$ -valued functions on compact open subsets with resp…

$A_{3}$ -formality for Demushkin groups at odd primes

Ambrus PÃ¡l, Gereon Quick

We study a weak form of formality for differential graded algebras, called $A_{3}$ -formality, for the cohomology of pro-p Demushkin groups at odd primes p. We show that the different…

Quasi-Boolean groups

Ambrus PÃ¡l, Gereon Quick

We give several equivalent characterisations of the maximal pro-2 quotients of real projective groups. In particular, for pro-2 real projective groups we provide a presentation in…

Power structures on the Grothendieck--Witt ring and the motivic Euler characteristic

Jesse Pajwani, Ambrus PÃ¡l

For $k$ a field, we construct a power structure on the Grothendieck--Witt ring of $k$ which has the potential to be compatible with symmetric powers of varieties and the motivic Eu…
