We work throughout over the complex numbers C, i.e. all schemes are over C and all maps of schemes are maps of C-schemes. A curve, unless otherwise stated, is a smooth complete curve. Points mean geometric points. We will, as is usual in such situations, toggle between the algebraic and analytic categories without warning. For a quasi-projective algebraic variety Y , the (mixed) Hodge structure...
We describe a new explicit function that given an elliptic curve E defined over Fpn , maps elements of Fpn into E in deterministic polynomial time and in a constant number of operations over Fpn . The function requires to compute a cube root. As an application we show how to hash deterministically into an elliptic curve.
We studied the use of gas curve subtraction to distinguish between two fractions soluble in neutral detergent solution. Samples of unfractionated (whole) forage, residue insoluble in 90% ethanol, and isolated NDF were fermented in vitro, and gas production was monitored. The gas volume associated with the ethanol solubles (A fraction) was determined as the difference between the gas from the wh...
The conjectural equivalence of curve counting on Calabi-Yau 3-folds via stable maps and stable pairs is discussed. By considering Calabi-Yau 3-folds with K3 fibrations, the correspondence naturally connects curve and sheaf counting on K3 surfaces. New results and conjectures (with D. Maulik) about descendent integration on K3 surfaces are announced. The recent proof of the Yau-Zaslow conjecture...
Abstract We study hyperelliptic curves $$y^2 = f(x)$$ y 2 = f ( x ) over local fields of odd residue characteristic. introduce the notion a “cluster picture” asso...
