Geometric quadratic Chabauty and $p$-adic heights
Abstract
Let be a curve of genus over whose Jacobian has Mordell--Weil rank and N\'eron--Severi rank . When , the geometric quadratic Chabauty method determines a finite set of -adic points containing the rational points of . We describe algorithms for geometric quadratic Chabauty that translate the geometric quadratic Chabauty method into the language of -adic heights and -adic (Coleman) integrals. This translation also allows us to give a comparison to the (original) cohomological method for quadratic Chabauty. We show that the finite set of -adic points produced by the geometric method is contained in the finite set produced by the cohomological method, and give a description of their difference.

Update definition of simple open. This clarifies that simple opens are everywhere locally soluble, which is not explicitly noted in the published version
