On the generalized Davenport constant and the Noether number
Known results on the generalized Davenport constant relating zero- sum sequences over a finite abelian group are extended for the generalized Noether number relating rings of polynomial invariants of an arbitrary finite group.

Finite torsors over strongly $F$-regular singularities [PDF]
We investigate finite torsors over big opens of spectra of strongly $F$-regular germs that do not extend to torsors over the whole spectrum. Let $(R,\mathfrak{m},k)$ be a strongly $F$-regular $k$-germ where $k$ is an algebraically closed field of ...

Covariants, Invariant Subsets, and First Integrals [PDF]
Let $k$ be an algebraically closed field of characteristic 0, and let $V$ be a finite-dimensional vector space. Let $End(V)$ be the semigroup of all polynomial endomorphisms of $V$.

When are the natural embeddings of classical invariant rings pure?
Consider a reductive linear algebraic group G acting linearly on a polynomial ring S over an infinite field; key examples are the general linear group, the symplectic group, the orthogonal group, and the special linear group, with the classical ...

Abstract Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment‐based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring ...

Treatment of equine sarcoids using recombinant poxviruses expressing feline interleukin‐2
Background – Interleukin (IL)‐2 stimulates antitumour immunity and is successfully used for the treatment of different neoplasias. Hypothesis/Objectives –Canarypox virus locally expressing feline IL‐2 is safe and can be used to treat equine sarcoids. Conclusions –Treatment of equine sarcoids with recombinant canarypox virus expressing feline IL‐2 seems

Some torsion classes in the Chow ring and cohomology of BPGLn
Abstract In the integral cohomology ring of the classifying space of the projective linear group PGLn (over C), we find a collection of p‐torsion classes yp,k of degree 2(pk+1+1) for any odd prime divisor p of n, and k⩾0. If, in addition, p2∤n, there are p‐torsion classes ρp,k of degree pk+1+1 in the Chow ring of the classifying stack of PGLn, such ...

STABILITY PATTERNS IN REPRESENTATION THEORY
We develop a comprehensive theory of the stable representation categories of several sequences of groups, including the classical and symmetric groups, and their relation to the unstable categories.
