Improvements of the Weil bound for Artin–Schreier curves

Abstract For the Artin–Schreier curve yq − y = f(x) defined over a finite field %${{\mathbb F}_q}%$ of q elements, the celebrated Weil bound for the number of %${{\mathbb F}_{q^r}}%$-rational points can be sharp, especially in super-singular cases and when r is divisible. In this paper, we show how...

520			\|a Abstract For the Artin–Schreier curve yq − y = f(x) defined over a finite field %${{\mathbb F}_q}%$ of q elements, the celebrated Weil bound for the number of %${{\mathbb F}_{q^r}}%$-rational points can be sharp, especially in super-singular cases and when r is divisible. In this paper, we show how the Weil bound can be significantly improved, using ideas from moment L-functions and Katz’s work on ℓ-adic monodromy calculations. Roughly speaking, we show that in favorable cases (which happens quite often), one can remove an extra %${\sqrt{q}}%$ factor in the error term.

title_auth	Improvements of the Weil bound for Artin–Schreier curves
abstract	Abstract For the Artin–Schreier curve yq − y = f(x) defined over a finite field %${{\mathbb F}_q}%$ of q elements, the celebrated Weil bound for the number of %${{\mathbb F}_{q^r}}%$-rational points can be sharp, especially in super-singular cases and when r is divisible. In this paper, we show how the Weil bound can be significantly improved, using ideas from moment L-functions and Katz’s work on ℓ-adic monodromy calculations. Roughly speaking, we show that in favorable cases (which happens quite often), one can remove an extra %${\sqrt{q}}%$ factor in the error term. © The Author(s) 2010

In this paper, we show how the Weil bound can be significantly improved, using ideas from moment L-functions and Katz’s work on ℓ-adic monodromy calculations. Roughly speaking, we show that in favorable cases (which happens quite often), one can remove an extra %${\sqrt{q}}%$ factor in the error term.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Monodromy Group</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Distinguished Triangle</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Inertia Group</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Quadratic Character</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Local Monodromy</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wan, Daqing</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Mathematische Annalen</subfield><subfield code="d">Berlin : Springer, 1869</subfield><subfield code="g">351(2010), 2 vom: 23.
