THE LIPMAN–ZARISKI CONJECTURE IN GENUS ONE HIGHER [PDF]

Forum of Mathematics, Sigma, 2020
We prove the Lipman–Zariski conjecture for complex surface singularities with $p_{g}-g-b\leqslant 2$. Here $p_{g}$ is the geometric genus, $g$ is the sum of the genera of exceptional curves and $b$ is the first Betti number of the dual graph.

Irreducible Jacobian derivations in positive characteristic

Open Mathematics, 2014
We prove that an irreducible polynomial derivation in positive characteristic is a Jacobian derivation if and only if there exists an n-1-element p-basis of its ring of constants. In the case of two variables we characterize these derivations in terms of

Treatment of equine sarcoids using recombinant poxviruses expressing feline interleukin‐2

Veterinary Dermatology, Volume 32, Issue 3, Page 283-e77, June 2021., 2021
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

Images of Locally Finite Derivations of Polynomial Algebras in Two Variables [PDF]

, 2010
In this paper we show that the image of any locally finite $k$-derivation of the polynomial algebra $k[x, y]$ in two variables over a field $k$ of characteristic zero is a Mathieu subspace.

In vitro antimicrobial activity of a gel containing antimicrobial peptide AMP2041, chlorhexidine digluconate and Tris‐EDTA on clinical isolates of Pseudomonas aeruginosa from canine otitis

Veterinary Dermatology, Volume 27, Issue 5, Page 391-e98, October 2016., 2016
Background– Pseudomonas aeruginosa (PA) may cause suppurative otitis externa with severe inflammation and ulceration in dogs. Multidrug resistance is commonly reported for this organism, creating a difficult therapeutic challenge. Objective– The aim of this study was to evaluate the in vitro antimicrobial activity of a gel containing 0.5 µg/mL of ...

Powersum formula for differential resolvents

International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 7, Page 365-371, 2004., 2004
We will prove that we can specialize the indeterminate α in a linear differential α‐resolvent of a univariate polynomial over a differential field of characteristic zero to an integer q to obtain a q‐resolvent. We use this idea to obtain a formula, known as the powersum formula, for the terms of the α‐resolvent.

Separating invariants for the basic G_a-actions [PDF]

, 2010
We explicitly construct a finite set of separating invariants for the basic $\Ga$-actions. These are the finite dimensional indecomposable rational linear representations of the additive group $\Ga$ of a field of characteristic zero, and their invariants

Some conditions under which Jordan derivations are zero

Journal of Taibah University for Science, 2017
In the current article, we obtain the following results: Let A be an algebra and P be a semi-prime ideal of A. Suppose that d:A→(A/P) is a Jordan derivation such that dim{d(a)|a∈A}≤1. If d(P)={0}, then d is zero.

On dependent elements in rings

International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 54, Page 2895-2906, 2004., 2004
Let R be an associative ring. An element a ∈ R is said to be dependent on a mapping F : R → R in case F(x)a = ax holds for all x ∈ R. In this paper, elements dependent on certain mappings on prime and semiprime rings are investigated. We prove, for example, that in case we have a semiprime ring R, there are no nonzero elements which are dependent on ...

A partial factorization of the powersum formula

International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 58, Page 3075-3101, 2004., 2004
For any univariate polynomial P whose coefficients lie in an ordinary differential field 𝔽 of characteristic zero, and for any constant indeterminate α, there exists a nonunique nonzero linear ordinary differential operator ℜ of finite order such that the αth power of each root of P is a solution of ℜzα = 0, and the coefficient functions of ℜ all lie ...
