Multiplicities of some graded сocharacters of the matrix superalgebra M(2,2)(F) [PDF]
Let $F$ be an arbitrary field of characteristic zero, and let $M^{(m,k)}(F)$ be a matrix superalgebra over $F$. It is known from the theory of algebras with polynomial identities that the superalgebra $M^{(m,k)}(F)$ has a finite basis of $Z_2$-graded ...

The ecology of hope: Building rainbows in education systems
Abstract Hope is frequently invoked in education, yet rarely theorised. Where it has been theorised, it has been understood in two largely separate ways: as an individual psychological capacity, in the positive‐psychology tradition and as a critical‐emancipatory stance, in the pedagogy of hope.

ABSTRACT Corporate sustainability research is rich but fragmented where influential frameworks illuminate important aspects of sustainability dynamics, yet they are often used in parallel rather than connected through a shared explanatory logic of change. This paper addresses that corporate sustainability puzzle through a targeted literature review and

Squares of characters that are the sum of all irreducible characters
Consider the groups satisfying the following condition: (*) Let \(G\) be a nonidentity finite group for which there exists an irreducible character \(\chi\) such that \(\chi^2=\sum_{\psi\in\text{Irr}(G)}\psi\). It follows from (*) that \(\chi\) is faithful, real-valued (Theorem 2.4) and the center of \(G\) must be trivial.

Chiari I Malformation: Review and Update of Current Treatment Options
ABSTRACT The pathophysiology of Chiari malformation type I (CM‐I) is complex, involving structural abnormalities at the craniovertebral junction that result in herniation of the cerebellar tonsils through the foramen magnum. In this study, we aim to present and evaluate current treatment options for CM‐I, with a focus on evidence‐based clinical ...

A saturation property for powers of irreducible characters.
A (reducible) character of a semisimple Lie algebra is saturated if for each of its dominant weights, the corresponding irreducible character is a summand in its orthogonal decomposition. A character is eventually saturated if some power is saturated. It is shown that any irreducible character whose highest weight is in the interior of the Weyl chamber

ABSTRACT The relationship between board governance and corporate carbon emission disclosure remains persistently inconsistent across the empirical literature, despite decades of accumulated evidence. Drawing on agency, stakeholder, legitimacy, institutional, and upper echelons perspectives within a single analytical framework, we conduct a three‐level ...

ABSTRACT Behavioural sustainability has emerged as a strategically significant construct for understanding how sustainability becomes embedded in organisational routines, decisions, and governance systems rather than remaining at the level of symbolic commitment.

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.
