Conference Contemporary Mathematics · January 1, 2026 We compute an analogue of Pascal’s triangle enriched in bilinear forms over a finite field. This gives an arithmetically meaningful count of the ways to choose j ring homomorphisms into an algebraic closure from an étale extension of degree n. We also comp ... Full text Cite

Desuspensions of S 1 Λ (P1/Q - {0, 1, ∞ })

Conference International Journal of Mathematics · June 1, 2016 We use the Galois action on Q1 -{0, 1,∞}) to show that the homotopy equivalence S1 Λ (Gm, Gm, S1 (1 -{0, 1,∞}) coming from purity, does not desuspend to a map Gm, Gm, 1 -{0, 1,∞}. ... Full text Cite

Galois Action on the Homology of Fermat Curves

Conference · January 1, 2016 In his paper titled â€œTorsion points on Fermat Jacobians, roots of circular units and relative singular homology,â€ Anderson determines the homology of the degree n Fermat curve as a Galois module for the action of the absolute Galois group (Forumal ... Full text Cite
