1. Fibras cuánticas para sistemas clásicos: introducción a la cuantificación geométrica
In this article, We shall introduce the formalism of canonical quantization called "geometric quantization". Since this formalism let us understand quantum mechanics as a geometric extension of classical mechanics, we shall identify the insufficiencies of the latter that are resolved by such an extension. We shall show that geometric quantization permits us

2. Comutatividade fraca por bijeção entre grupos abelianos / Weak commutativity by bijection between Abelian groups
O grupo de comutatividade fraca por bijeção G(H;K;σ) = {H;K|[h;hσ] = 1, para todo h pertence H} é definido como sendo o quociente do produto livre H * K pelo fecho normal de {[h;hσ] : para todo h pertence H} emH * K. Nessa dissertação, estudamos os resultados obtidos em 2009 por Oliveira e Sidki [7] que suportam a seguinte conjectura: Se

3. Comutatividade fraca por bijeção entre grupos abelianos / Weak commutativity by bijection between Abelian groups
The group of weak commutativity for bijection G(H;K;σ) = {H;K|[h;hσ] = 1, for all h H} belongs is defined as the quotient of the free product H * K the normal closure of {[h;hσ] : h belongs to all H} in H * K. In this dissertation, we studied the results obtained in 2009 by Sidka and Oliveira [7] that support the following conjecture: If H,K ~

4. Pode a não-comutatividade do espaço indicar a dependência funcional da entropia com a área
Calculation of the entropy of black holes is an open subject. Such problem is very interesting due to its relationship with basic problems like; the construction of a quantum theory of the gravity, statistical approach of the calculation of black holes entropy and the validity (or non validity) of the holographic principle. In this work we are looking for a

5. Modified symplectic structures in cotangent bundles of lie groups
In earlier work [1], we studied an extension of the canonical symplectic structure in the cotangent bundle of an affine space Q = R N, by additional terms implying the Poisson non-commutativity of both configuration and momentum variables. In this article, we claim that such an extension can be done consistently when Q is a Lie group G.

6. O contrato de seguro em face da nova perspectiva social e jurídica
The text presents an evolutionistic overview of the insurance contract, from the birth of the Roman Law to the conceptual changes introduced by the Consumer Defense Code, the 2002 Civil Code, and the Statute on Elderly Citizens, mainly in regard to mass insurance. Although neither explicit nor underlying the only intention of stressing the consumerist ideals

7. Physics of deformed special relativity: relativity principle revisited
In many different ways, Deformed Special Relativity (DSR) has been argued to provide an effective limit of quantum gravity in almost-flat regime. Unfortunately, DSR is up to now plagued by many conceptual problems (in particular how it describes macroscopic objects) which forbids a definitive physical interpretation and clear predictions. Here we propose a c

8. The classical and commutative limits of noncommutative quantum mechanics: a superstar * Wigner-Moyal equation
We are interested in the similarities and differences between the quantum-classical (Q-C) and the noncommutative-commutative (NC-Com) correspondences. As one useful platform to address this issue we derive the superstar Wigner-Moyal equation for noncommutative quantum mechanics (NCQM). A superstar *-product combines the usual phase space * star and the nonco
