Rigidity and Real Residue Class Fields
Introduction and acknowledgements: Consider a cover φ : X → Px of the Riemann sphere (uniformized by x) by a projective nonsingular curve X with r > 2 branch points. Assume that both the curves and the map are defined over Q. Generalizing Serre [Se] we consider not necessarily Galois covers with any number r of branch points (not necessarily in R). We show how to compute the action of complex c...
متن کاملQuadratic Residue Covers for Certain Real Quadratic Fields
Let A„{a, b) = {ban+(a-l)/b)2+4an with n > 1 and ¿>|a-l . If W is a finite set of primes such that for each n > 1 there exists some q £W for which the Legendre symbol {A„{a, b)/q) ^ -1 , we call <£ a quadratic residue cover (QRC) for the quadratic fields K„{a, b) = Q{^jA„{a, b)). It is shown how the existence of a QRC for any a, b can be used to determine lower bounds on the class number of K„{...
متن کاملRigidity and lack of rigidity for solenoidal matrix fields
We study the problem of identifying conditions under which a divergence free matrix field takes values in some prescribed sets of matrices K. We treat in detail the case when K is made of two or three matrices. Our results are parallel to those on curl free matrices. In that case Ball and James showed rigidity when K is made of two matrices and Tartar proved lack of rigidity when K is made of f...
متن کاملQuintic Polynomials and Real Cyclotomic Fields with Large Class Numbers
We study a family of quintic polynomials discoverd by Emma Lehmer. We show that the roots are fundamental units for the corresponding quintic fields. These fields have large class numbers and several examples are calculated. As a consequence, we show that for the prime p = 641491 the class number of the maximal real subfield of the pth cyclotomic field is divisible by the prime 1566401. In an a...
متن کاملRigidity for real polynomials
We prove the topological (or combinatorial) rigidity property for real polynomials with all critical points real and nondegenerate, which completes the last step in solving the density of Axiom A conjecture in real one-dimensional dynamics.
