Group actions on $p$ -adic symplectic manifolds

Luis Crespo, Álvaro Pelayo

Let $p$ be a prime number. We introduce symplectic actions of $p$ -adic analytic Lie groups on $p$ -adic symplectic manifolds. Then we show that any $p$ -adic symplectic action $G\tim…

$p$ -adic angular momentum coupling in symplectic geometry

Luis Crespo, Álvaro Pelayo

The coupled angular momentum is an integrable system with two degrees of freedom which is fundamental in physics and the theory of integrable systems. It is obtained by coupling tw…

Darboux's Theorem in $p$ -adic symplectic geometry

Luis Crespo, Álvaro Pelayo

We prove a non Archimedean Darboux's Theorem: any two symplectic forms on a $p$ -adic analytic manifold are locally isomorphic. Understanding local problems such as the existence of…

Rigidity and flexibility in $p$ -adic symplectic geometry

Luis Crespo, Álvaro Pelayo

Let $n \geq 2$ be an integer and let $p$ be a prime number. We prove that the analog of Gromov's non-squeezing theorem does not hold for $p$ -adic embeddings: for any $p$ -adic absolut…

$p$ -adic symplectic geometry of integrable systems and Weierstrass-Williamson theory I

Luis Crespo, Álvaro Pelayo

The local symplectic theory of integrable systems is fundamental to understand their global theory, as well as the behavior near singularities of fundamental models from classical…
