S -versions and S -generalizations of nil-clean ideals and Nil*-Noetherian rings Tushar Singh, Shiv Datt Kumar Asian European Journal of Mathematics, 2026 We propose the idea of [Formula: see text]-nil-clean ideals in this work. We prove that Jacobson’s Lemma holds for [Formula: see text]-nil-clean elements. Furthermore, we define the [Formula: see text]-version of a Boolean ring and prove that every ideal of an [Formula: see text]-Boolean ring is an [Formula: see text]-nil-clean ideal. In addition, we show that a class of von Neumann regular local rings with maximal ideal [Formula: see text] disjoint from [Formula: see text] belongs to the class of [Formula: see text]-clean rings. Subsequently, we define the concept of a Nil[Formula: see text]-[Formula: see text]-Noetherian ring, which serves as a proper generalization of both Nil[Formula: see text]-Noetherian and [Formula: see text]-Noetherian rings. Among our main results, we demonstrate the existence of [Formula: see text]-primary decomposition in Nil[Formula: see text]-[Formula: see text]-Noetherian rings, thereby generalizing the classical Lasker–Noether theorem.
Non-abelian extension theory of Lie rings Dev Karan Singh, Mani Shankar Pandey, Shiv Datt Kumar Journal of Algebra and Its Applications, 2026 In this paper, we establish fundamental results concerning non-abelian extensions of Lie rings. Specifically, we demonstrate one-to-one correspondence between the equivalence classes of non-abelian extensions of Lie ring [Formula: see text] by Lie ring [Formula: see text] and the elements of second cohomology group [Formula: see text], where [Formula: see text] acts on [Formula: see text]. Additionally, we provide necessary and sufficient condition under which such extensions exist, particularly when a specific abstract kernel is involved.
Lasker–Noether Theorem for Nonnil--Noetherian Rings T. Singh, S. D. Kumar Siberian Mathematical Journal, 2026 We introduce the concept of $ S $ -primary decomposition for a commutative ring and show that if a ring admits an $ S $ -primary decomposition, then it admits a minimal $ S $ -primary decomposition. We establish the $ S $ -version of Krull’s intersection theorem by using the existence of $ S $ -primary decomposition in $ S $ -Noetherian domains. As the main result, we prove the Lasker–Noether theorem for nonnil- $ S $ -Noetherian rings, thereby extending the classical Lasker–Noether theorem.

A study of S-primary decompositions Tushar Singh, Ajim Uddin Ansari, Shiv Datt Kumar Czechoslovak Mathematical Journal, 2025 summary:Let $R$ be a commutative ring with identity, and let $S \subseteq R$ be a multiplicative set. An ideal $Q$ of $R$ (disjoint from $S$) is said to be $S$-primary if there exists an $s\in S$ such that for all $x,y\in R$ with $xy\in Q$, we have $sx\in Q$ or $sy\in {\rm rad}(Q)$. Also, we say that an ideal of $R$ is $S$-primary decomposable or has an $S$-primary decomposition if it can be written as a finite intersection of $S$-primary ideals. First we provide an example of an $S$-Noetherian ring in which an ideal does not have a primary decomposition. Then our main aim is to establish the existence and uniqueness of $S$-primary decomposition in $S$-Noetherian rings as an extension of a historical theorem of Lasker-Noether.
