Title in Portuguese
Sobre uma classe de teorias da mecânica
Keywords in Portuguese
Mecânica clássica
Mecânica quântica
Abstract in Portuguese
Neste trabalho mostra-se que uma devida reinteração das leis da Mecânica quando formuladas como um princípio variacional define uma classe de funcionais que as satisfazem. Cada funcional define uma teoria da Mecânica, chamada Mecânica Generalizada, que descreve uma particular dinâmica. A Mecânica Clássica, que descreve uma dinâmica chamada conjuntiva, baseia-se em uma escolha chamada trivial deste funcional. Escolhas não-triviais definem teorias que descrevem dinâmicas chamadas convolutivas. Uma dessas escolhas não-triviais define uma teoria que descreve uma dinâmica convolutica que se pode chamar quântica. Essa teoria é formalmente idêntica à Mecânica Quântica mas apresenta um conteúdo epistemológico diferente. A interpretação probabilística da Mecânica Quântica surge como uma interpretação suficiente mas não necessária desse formalismo.

Abstract in English
In this work it is shown that a proper reinterpretation of the laws of Mechanics when formulated as a variational principle defines a class of functionals wich satisfies them. Each functional defines one theory of Mechanics, called Generalized Mechanics, which describes a particular dynamics. The Classical Mechanics, which describes to so called conjunctive dynamics, is based on a trivial choice of this functiona. Non-trivial choices define theories which describe the so called convolutive dynamics. One of these non-trivial choices define a convolutive theory which may be called quantic. This theory is formally identical to Quantum Mechanics but it displays a different epistemological content. The probabilistic interpretation of Quantum Mechanics emerges as a sufficient but not necessary interpretation of this formalism.
