RECURSIONS FOR CHARACTERISTIC NUMBERS OF GENUS ONE PLANE CURVES
CHARACTERISTIC PLANE CURVES
font style='font-size:12px;'>
2015/7/14
Characteristic numbers of families of maps of nodal curves to P2 are dened as
intersection of natural divisor classes. (This denition agrees with the usual denition for
families of plane curves.)...
GENUS 0 AND 1 HURWITZ NUMBERS: RECURSIONS, FORMULAS, AND GRAPH-THEORETIC INTERPRETATIONS
RECURSIONS FORMULAS GRAPH-THEORETIC
font style='font-size:12px;'>
2015/7/14
We derive a closed-form expression for all genus 1 Hurwitz numbers, and give a
simple new graph-theoretic interpretation of Hurwitz numbers in genus 0 and 1. (Hurwitz
numbers essentially count irred...

Urban legislators have long lamented that they do not get their fair share of bills passed in state governments, often blaming rural and suburban interests for blocking their efforts. Now, a new study...
Generalization of Proth's and Miller's theorems for $Kp^n+1$ numbers
Proth's Miller's theorems
font style='font-size:12px;'>
2010/11/24
In this paper we generalize classical results by Miller and Proth for integers of the form $N=Kp^n+1$. The first generalization of Proth's theorem requires the use of a base which is a $p$-th power n...

The Atiyah conjecture predicts that the L2-Betti numbers of a finite CW-complex with torsion-free fundamental group are integers. We show that the Atiyah conjecture holds (with an additional technica...

It is not commonly realized that the algebra of complex numbers can be used in an elegant way to represent the images of ordinary 3-dimensional figures, orthographically projected to the plane. We de...
