An addition theorem for the elementary abelian group

open access: yesJournal of Combinatorial Theory, 1968
Summary: Let \(S(a_1,\ldots, a_s)\) be the set of all sums over subsequences of a sequence \(\{a_1,\ldots, a_s\}\), \(a_1\neq 0\), from an abelian group \(G\). The author proves: If \(G\) is an abelian group of order \(p^n\) \((n\geq 2)\) then: (i) If \(s\geq 2^{n-1}(p-1)\) then \(S(a_1,\ldots, a_s)\) includes a coset of a subgroup of order \(p\). (ii)

Topological K‐theory of quasi‐BPS categories for Higgs bundles

open access: yesJournal of Topology, Volume 18, Issue 4, December 2025.
Abstract In a previous paper, we introduced quasi‐BPS categories for moduli stacks of semistable Higgs bundles. Under a certain condition on the rank, Euler characteristic, and weight, the quasi‐BPS categories (called BPS in this case) are noncommutative analogues of Hitchin integrable systems.

Structure theorems for braided Hopf algebras

open access: yesJournal of Topology, Volume 18, Issue 4, December 2025.
Abstract We develop versions of the Poincaré–Birkhoff–Witt and Cartier–Milnor–Moore theorems in the setting of braided Hopf algebras. To do so, we introduce new analogs of a Lie algebra in the setting of a braided monoidal category, using the notion of a braided operad.

Actions of elementary Abelian p-groups

open access: yesTopology, 1988
An n-dimensional near-manifold X is a locally compact topological space X such that for a closed subset \(S\subset X\), \(\dim S\leq n-2,\) X-S is a non-empty n-dimensional manifold. This definition has its usual generalizations and it is motivated by considering complex varieties with singular set S. The author continues the study of actions of \(G=({\

A history of Galois fields

open access: yesKhronos, 2016
This paper stresses a specific line of development of the notion of finite field, from Évariste Galois’s 1830 “Note sur la théorie des nombres,” and Camille Jordan’s 1870 Traité des substitutions et des équations algébriques, to Leonard Dickson’s 1901 ...
