On a Class of Graphs with Large Total Domination Number [PDF]
Discrete Mathematics & Theoretical Computer Science, 2018 Let $\gamma(G)$ and $\gamma_t(G)$ denote the domination number and the total domination number, respectively, of a graph $G$ with no isolated vertices. It is well-known that $\gamma_t(G) \leq 2\gamma(G)$.

Class Number and Ramification in Number Fields [PDF]
Nagoya Mathematical Journal, 1963 In the ring Ok of algebraic integers of a number field K the group Ik of ideals of Ok modulo the subgroup Pk of principal ideals is a finite abelian group of order hk, the class number of K. The determination of this number is an outstanding problem of algebraic number theory.

Lower Bound for the Class Number of ℚn2+4
International Journal of Mathematics and Mathematical Sciences, 2020 In this paper, we give an explicit lower bound for the class number of real quadratic field ℚd, where d=n2+4 is a square-free integer, using ωn which is the number of odd prime divisors of n.

Deciding on the Starting Number of Classes of a Latent Class Tree [PDF]
Sociological Methodology, 2018 In recent studies, latent class tree (LCT) modeling has been proposed as a convenient alternative to standard latent class (LC) analysis. Instead of using an estimation method in which all classes are formed simultaneously given the specified number of classes, in LCT analysis a hierarchical structure of mutually linked classes is obtained by ...

A class of weighted Delannoy numbers
Filomat, 2022 The weighted Delannoy numbers are defined by the recurrence relation fm,n = ? fm?1,n +? fm,n?1 + ? fm?1,n?1 if mn > 0, with fm,n = ?m?n if nm = 0. In this work, we study a generalization of these numbers considering the same recurrence relation but with fm,n = AmBn if nm = 0.

Mentoring for Faculty from Working-Class Backgrounds
, 2020 Faculty mentoring across gender, race, and culture is facilitated by formal mentoring programs. Mentoring across the cultural differences associated with social class, however, represents a largely unaddressed gap in the provision of formal faculty ...

A Necessary and Sufficient Condition for k=ℚ4n 2+1 to Have Class Number ωn+c
International Journal of Mathematics and Mathematical Sciences, 2022 In this paper, we give a necessary and sufficient condition for real quadratic field k=ℚ4n 2+1 to have class number ωn+c where c∈1, 2 and ωn is the number of odd prime divisors of n.
