Abstract
Conditionally on the Tate--Shafarevich and Bloch--Kato Conjectures, we give an explicit upper bound on the size of the -adic Chabauty--Kim locus, and hence on the number of rational points, of a smooth projective curve of genus in terms of , , the Mordell--Weil rank of its Jacobian, and the reduction types of at bad primes. This is achieved using the effective Chabauty--Kim method, generalising bounds found by Coleman and Balakrishnan--Dogra using the abelian and quadratic Chabauty methods.
