A class of weighted Delannoy numbers [PDF]
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.

Fair sharing in learning rational numbers in a 5th grade class
JETEN, 2023 Rational numbers are considered a difficult set to teach and learn, and these difficulties are identified in the literature as related to the nature of the set itself, as well as to its teaching. Thus, one of the difficulties relates to the fact that the

Diophantine Equations and Class Numbers [PDF]
Journal of Number Theory, 1986 In this paper, the author intends to extend some already known results. First he tries to provide sufficient conditions for non-trivial class numbers of real quadratic fields of Richaud-Degert type, in order to generalize results of Ankeny-Chowla-Hasse, S. D. Lang, H. Takeuchi and I. Yamaguchi.

Preprint: Machine Learning Class Numbers of Real Quadratic Fields
, 2022 We implement and interpret various supervised learning experiments involving real quadratic fields with class numbers 1, 2 and 3. We quantify the relative difficulties in separating class numbers of matching/different parity from a data-scientific ...

Some Criteria for Class Numbers to Be Non-One
Journal of Mathematics, 2020 Let d be a positive integer which is not a perfect square and n be any nonzero fixed integer. Then, the equation x2−dy2=n is known as the general Pell equation. In this paper, we give some criteria for class numbers of certain real quadratic fields to be

On the computation of the class numbers of some cubic fields
International Journal of Mathematics and Mathematical Sciences, 1986 Class numbers are calculated for cubic fields of the form x3+12Ax−12=0, A>0, for 1≤a≤17, and for some other values of A. These fields have a known unit, which under certain conditions is the fundamental unit, and are important in studying the Diophantine

Indices formal grammar of the Universal Decimal Classification
Библиосфера, 2018 The article proposes an algorithm for decoding and representation in natural language of the Universal Decimal Classifycation (UDC) complex class numbers. The algorithm is based on the formal definition of correct class numbers using a generative grammar,
