Abstract: This work conducts a mathematical characterization of the set B of Boltzmann functions, formed by strictly increasing real functions that satisfy the multiplicative additivity property f (xy) = f (x) + f (y). The study investigates the analytical and topological properties of this set and establishes a formal connection with the informational formulation of Shannon’s entropy. Using methods from real analysis and probability theory, it is demonstrated that the functions in B are analytic and of class C ∞ , and that the set is convex and connected, although it is not open, closed, or compact in the topology of uniform convergence on compact sets. The fundamental characterization reveals that the domain of B is the interval (0, ∞) and that B = {k ln x | k > 0}. From this basis, it is proven that Shannon’s entropy, when restricted to independent random variables, inherits the mathematical structure of B through a one-to-one correspondence. It is concluded that the logarithmic form of entropy is uniquely determined by its monotonicity and additivity, and that Shannon’s formulation generalizes that of Boltzmann-Gibbs by accommodating systems with arbitrary correlations, unifying the foundations of statistical thermodynamics and information theory.2026-03-16T00:00:00ZDo Jaynes–Cummings ao modelo de Dicke: emaranhamento e efeitos coletivos em sistemas Qubit–Bósonhttps://repositorio.ufu.br/handle/123456789/492662026-08-05T06:21:30Z2026-07-31T00:00:00ZTitle: Do Jaynes–Cummings ao modelo de Dicke: emaranhamento e efeitos coletivos em sistemas Qubit–Bóson2026-07-31T00:00:00ZUso de experimentos no ensino das leis de Newtonhttps://repositorio.ufu.br/handle/123456789/488622026-07-16T06:27:11Z2024-05-03T00:00:00ZTitle: Uso de experimentos no ensino das leis de Newton
Abstract: Physics teaching has often not attracted or motivated students, with the teaching methodology being one of the factors that contribute to learning difficulties. The use of experiments can be explored as a strategy to awaken students' interest in the subject. This work presents the construction of a didactic sequence (SD) with the theme of Newton's Laws, developed through experiments. The sequence was planned for eight regular 50-minute classes: the first class consists of the application of an initial questionnaire to understand the students' perception of the topic; the following six classes are intended for carrying out and discussing three experiments, one for each Newton's law; and the last class is theoretical in nature, including the reapplication of the questionnaire in order to evaluate learning. Although the sequence has not yet been tested, it is expected, based on studies and observations of pedagogical practices, that it will contribute to improving the teaching and learning of Newton's Laws.2024-05-03T00:00:00Z
