Gasterophilus flavipes (Oestridae: Gasterophilinae): A horse stomach bot fly brought back from oblivion with morphological and molecular evidence. [PDF]

PLoS ONE, 2019
Species of Gasterophilus Leach are obligate parasites in domestic and wild equids and responsible for cosmopolitan gasterophilosis. Although with only eight species known so far, they have received considerable attention because of their significant ...

Turning weight multiplicities into Brauer characters [PDF]

Journal of Algebra, 2020
We describe two methods for computing $p$-modular Brauer character tables for groups of Lie type $G(p^f)$ in defining characteristic $p$, assuming that the ordinary character table of $G(p^f)$ is known, and the weight multiplicities of the corresponding algebraic group $G$ are known for $p$-restricted highest weights.

SQUARES OF DEGREES OF BRAUER CHARACTERS AND MONOMIAL BRAUER CHARACTERS [PDF]

Bulletin of the Australian Mathematical Society, 2019
Let $G$ be a finite group and let $p$ be a prime factor of $|G|$. Suppose that $G$ is solvable and $P$ is a Sylow $p$-subgroup of $G$. In this note, we prove that $P{\vartriangleleft}G$ and $G/P$ is nilpotent if and only if $\unicode[STIX]{x1D711}(1)^{2}$ divides $|G:\ker \unicode[STIX]{x1D711}|$ for all irreducible monomial $p$-Brauer characters ...

Irreducible Characters with Cyclic Anchor Group

Axioms, 2023
We consider G to be a finite group and p as a prime number. We fix ψ to be an irreducible character of G with its restriction to all p-regular elements of G and ψ0 to be an irreducible Brauer character.

Spaces of states of the two-dimensional $O(n)$ and Potts models

SciPost Physics, 2023
We determine the spaces of states of the two-dimensional $O(n)$ and $Q$-state Potts models with generic parameters $n,Q\in \mathbb{C}$ as representations of their known symmetry algebras.

A generalization of Brauer characters [PDF]

Transactions of the American Mathematical Society, 1965
1. Statement of results. The Brauer characters, or modular characters, of a finite group G with respect to a prime p are defined only on the p-regular elements of G. Brauer [1], [3] has overcome this limitation to some extent by using the Brauer characters of certain subgroups of G, in terms of which he has defined the generalized decomposition matrix ...

NONVANISHING ELEMENTS FOR BRAUER CHARACTERS [PDF]

Journal of the Australian Mathematical Society, 2015
Let $G$ be a finite group and $p$ a prime. We say that a $p$-regular element $g$ of $G$ is $p$-nonvanishing if no irreducible $p$-Brauer character of $G$ takes the value $0$ on $g$. The main result of this paper shows that if $G$ is solvable and $g\in G$ is a $p$-regular element which is $p$-nonvanishing, then $g$ lies in a normal subgroup of $G$ whose

Révision de l’espèce Homo erectus (Dubois, 1893)

Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2000
The hypodigm for Homo erectus is a problem which remains unresolved. Most disagreements are based on chronological rather than morphological data. A methodology based neither on simple global similarity nor on chronological position is required to ...

Characters of Brauer’s centralizer algebras [PDF]

Pacific Journal of Mathematics, 1995
This paper, a portion of the author's doctoral dissertation, extends the methods for studying representations and irreducible characters of the symmetric group to the representations and irreducible characters of Brauer's centralizer algebras. The author defines analogues of conjugacy classes for the Brauer algebra, derives formulas for the irreducible
