Jordan derivations of polynomial rings

Karpatsʹkì Matematičnì Publìkacìï, 2012
We study connections between the set of Jordan derivations of a ring $R$ and the sets of Jordan derivations of a polynomial ring $R[x_1,\dots,x_n]$ and  formal power series ring $R[[x_1,\dots,x_n]]$. We also establish a condition when $JDer R$ is a left $

Moduli space of filtered λ-ringstructures over a filtered ring

International Journal of Mathematics and Mathematical Sciences, 2004
Motivated in part by recent works on the genus of classifying spaces of compact Lie groups, here we study the set of filtered λ-ring structures over a filtered ring from a purely algebraic point of view. From a global perspective, we first show that this

Multiplicative Structure and Hecke Rings of Generator Matrices for Codes over Quotient Rings of Euclidean Domains

Mathematics, 2017
In this study, we consider codes over Euclidean domains modulo their ideals. In the first half of the study, we deal with arbitrary Euclidean domains.

FACTORING POLYNOMIALS IN THE RING OF FORMAL POWER SERIES OVER ℤ [PDF]

International Journal of Number Theory, 2012
We consider polynomials with integer coefficients and discuss their factorization properties in ℤ[[x]], the ring of formal power series over ℤ. We treat polynomials of arbitrary degree and give sufficient conditions for their reducibility as power series.

Nondegenerate Ideals in Formal Power Series Rings

Rocky Mountain Journal of Mathematics, 2004
Let \(A\) be the formal power series ring \(\mathbb{C}[[x_1,\dots, x_n]]\) over \(\mathbb{C}\). For \(k=(k_1,\dots, k_n)\in \mathbb{Z}^n_+\), put \(x^k= x^{k_1}_1\cdots x^{k_n}_n\) and an element \(g= \sum a_{k_1,\dots, k_n} x^{k_1}_1\cdots x^{k_n}_n\) of \(A\) is written as \(g=\sum a_k x^k\). For an element \(g= \sum a_k x^k\) and an ideal \(I\) of \(

The skills required for transition to university and study in biological sciences: A student perspective

FEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

Catenarity of formal power series rings over a pullback

Journal of Pure and Applied Algebra, 1992
Let \((T,M,K)\) be a quasi local domain with maximal ideal \(M\) and residue class field \(K\). If \(\varphi\) is the natural surjection of \(T\) on \(K\), for any subring \(D\) of \(K\), \(\varphi^{-1}(D)=R\) is called the pull back. The main interest of the authors is in finding conditions for \(R[[X_ 1,\dots,X_ n]]\) catenarian.
