Hypersurfaces that are not stably rational
A fundamental problem of algebraic geometry is to determine which varieties are rational, that is, isomorphic to projective space after removing lower-dimensional subvarieties from both sides. In particular, we want to know which smooth hypersurfaces in projective space are rational. An easy case is that smooth complex hypersurfaces of degree at least n + 2 in P are not covered by rational curv...
متن کاملRational Quartic Reciprocity
In 1985, K. S. Williams, K. Hardy and C. Friesen [11] published a reciprocity formula that comprised all known rational quartic reciprocity laws. Their proof consisted in a long and complicated manipulation of Jacobi symbols and was subsequently simplified (and generalized) by R. Evans [3]. In this note we give a proof of their reciprocity law which is not only considerably shorter but also she...
متن کاملRational Quartic Reciprocity Ii
for every prime p ≡ 1 mod 4 such that (p/pj) = +1 for all 1 ≤ j ≤ r. This is ’the extension to composite values of m’ that was referred to in [3], to which this paper is an addition. Here I will fill in the details of a proof, on the one hand because I was requested to do so, and on the other hand because this general law can be used to derive general versions of Burde’s and Scholz’s reciprocit...
متن کاملVery low HbA1C, is it a problem?
Dear Editor An important problem to manage diabetes mellitus is controlling the patients` blood glucose. Fluctuation of blood glucose results in molecular biochemistry change and can result in unwanted diabetic complications (1). In clinical practice, hemoglobin A1C (HbA1C) is a common useful laboratory test to follow-up patients with diabetes (2). Sometimes, an unexpecte...
متن کاملRational Points on Quartic Hypersurfaces
Let X be a projective non-singular quartic hypersurface of dimension 39 or more, which is defined over Q. We show that X(Q) is non-empty provided that X(R) is non-empty and X has p-adic points for every prime p.
