Interlacing, integrals of Hurwitz series and differential equations

Colloquium Mathematicum, 2022
In this paper, we first introduce the unlacing of Hurwitz series, which can be viewed as an inverse of interlacing, and develop the basic properties of unlacing, interlacing and integral of Hurwitz series.

On a conjecture posed by Benhissi and Koja

, 2020
Let = (Rn)n≥0 be an ascending chain of commutative rings with identity and (resp., ) the generalized composite Hurwitz series ring (resp., generalized composite Hurwitz polynomial ring). In this paper, we completely characterize when the rings and are PS-

Hurwitz integrality of the power series expansion of the sigma function for a telescopic curve

Journal of the Mathematical Society of Japan, 2022
A telescopic curve is a certain algebraic curve defined by $m-1$ equations in the affine space of dimension $m$, which can be a hyperelliptic curve and an $(n,s)$ curve as a special case.

Polynomial and power series ring extensions from sequences

, 2020
Let [Formula: see text] be a commutative ring with identity. Let [Formula: see text] and [Formula: see text] be the collection of polynomials and, respectively, of power series with coefficients in [Formula: see text].

McCoy property of Hurwitz series rings

, 2020
Based on a theorem of McCoy on commutative rings, Nielsen called a ring R right McCoy if for any nonzero polynomials f(x),g(x) over R, f(x)g(x) = 0 implies f(x)r = 0 for some 0≠r ∈ R.

Clinical Observations on Postless Fiber-Reinforced Composite Restorations in Endodontically Treated Teeth with Immediate Pre-Endodontic Dentin Sealing and an Internal Adhesive Ferrule: A Case Series

Dental journal
Background: Traditional reliance on intraradicular posts for the restoration of root-filled teeth is decreasing due to advances in adhesive dentistry. Immediate pre-endodontic dentin sealing (IPDS) aims to protect dentin during endodontic procedures and ...
