25 Years of Quantum Groups: from Definition to Classification

open access: yesActa Polytechnica, 2008
In mathematics and theoretical physics, quantum groups are certain non-commutative, non-cocommutative Hopf algebras, which first appeared in the theory of quantum integrable models and later they were formalized by Drinfeld and Jimbo.

Zjawisko ukrytej przemocy wobec najmłodszych uczniów na zajęciach matematycznych

open access: yesProblemy Wczesnej Edukacji, 2019
The paper undertakes research meant to identify the teacher’s violent behaviour towards students during early school math lessons. The research conducted in grade one during the math class was used as an aid to deeper understanding of the phenomenon of ...

Digital Storytelling in Teaching and Learning Mathematics: A PRISMA Systematic Literature Review

open access: yesEducation Sciences
Digital storytelling (DST) has emerged as a promising pedagogical approach in mathematics education, combining narrative and digital media to enhance conceptual understanding, engagement, and reflective practice. This systematic review synthesises recent

The Limits of Mathematics---Third Version

open access: yes, 1994
This is yet another version of the course notes in chao-dyn/9407003. Here we change the universal Turing machine that is used to measure program-size complexity so that the constants in our information-theoretic incompleteness theorems are further reduced. This is done by inventing a more complicated version of lisp in which the parentheses associating

COMPUTATION OF PLASTIC LIMIT USING MATHEMATICAL MODEL

open access: yes, 2022
This paper presents a mathematical model that uses a British cone to predict the soil moisture-penetration relationship. This relationship is nonlinear for non-bentonite bearing soil and can be modelled using a sigmoidal mathematical function. The developed mathematical model gives a unique opportunity for computing and predicting the fall cone ...

DETERMINATION OF PLASTIC LIMIT USING MATHEMATICAL MODEL

open access: yes, 2023
Using a mathematical model which predicts the moisture-penetration relationship up to zero moisture content, a model which computes the plastic limit based on the penetration value at the plastic limit is proposed. The model was developed using 194 Atterberg limit test results and validated using 44 soil data collected from the literature.

An Explicit Form of Signum Function

open access: yesMathematics
In this paper, the author derives an analytical exact form of signum function, which evidently constitutes a fundamental concept of Communication Systems and Control Theory along with digital control systems and is also involved in many other fields of ...

Measure of stability of a Pareto optimal solution to a vector integer programming problem with fixed surcharges in the l1 and l∞ metrics [PDF]

open access: yesComputer Science Journal of Moldova, 2005
In this paper we consider a vector integer programming problem with Pareto principle of optimality for the case where partial criteria belong to the class of separable piecewise linear functions. The limit level of the initial data's perturbations in the
