Abstract

Let H = n 1 , n 2 , n 3 be a numerical semigroup. Let H be the interval completion of H, namely the semigroup generated by the interval n 1 , n 1 +1, . . . , n 3 . Let K be a field and K[H] the semigroup ring generated by H. Let I * H be the defining ideal of the tangent cone of K[H]. In this paper, we describe the defining equations of I * H . From that, we establish the Herzog-Stamate conjecture for monomial space curves stating that β i (I * H ) ≤ β i (I * H ) for all i, where β i (I * H ) and β i (I * H ) are the ith Betti numbers of I * H and I * H respectively.

“…purely but transformed into a "type of service" that provides Authors Nguyen Thanh Vu & Bui Quang Tam (2020) determined that the level of student satisfaction with support services at school includes the following factors: Organizational implementation process, Support staff, Facilities and equipment, Interactive information channels, Service accessibility and Movement activities. [3] According to authors Nguyen Bich Nhu & Nguyen Trung Hieu (2021), factors affecting student satisfaction include: enrollment, consulting, guidance; union work; student management; infrastructure; support team. [4] Based on the inheritance of published researches, the author proposes a research model with 05 specific components as follows::…”
