Abstract:We compute the expectation of the number of linear spaces on a random complete intersection in p-adic projective space. Here "random" means that the coefficients of the polynomials defining the complete intersections are sampled uniformly from the p-adic integers. We show that as the prime p tends to infinity the expected number of linear spaces on a random complete intersection tends to 1. In the case of the number of lines on a random cubic in three-space and on the intersection of two random quadrics in fou… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
