Batalin-Fradkin-Vilkovisky quantization of the generalized scalar electrodynamics

This work comprises a study upon the quantization and the renormalizability of the generalized electrodynamics of spinless charged particles (mesons), namely, the generalized scalar electrodynamics (GSQED4). The theory is quantized in the covariant framework of the Batalin-Fradkin-Vilkovisky method. Thereafter, the complete Green's functions are obtained through functional methods and a proper discussion on the theory's renormalizability is also given. Next, we present the computation and further discussion on the radiative correction at α order; and, as it turns out, an unexpected mP-dependent divergence on the mesonic sector of the theory is found. Furthermore, in order to show the effectiveness of the renormalization procedure on the present theory, we also give a diagrammatic discussion on the photon self-energy at α2 order, where we observe contributions from the meson self-energy function. Afterwards, we present the expressions of the counterterms and effective coupling of the theory, obtaining from the latter an energy range where the theory is defined by m2≤k2

Desenvolvimento econômico e desigualdade social: um estudo sobre os aspectos sociais presentes na obra de Raúl Prebisch

This study aims to conduct an analysis on the social aspects present in the works of the Argentine economist Raúl Prebisch (1901-1986). Based on the author's research on the economic development of the peripheral countries, it will be demonstrated how the social and economic factors have interconnected in the developmental theory of the peripheral worldwide economy. To achieve this goal, the six works of Prebisch considered essentials by Economic Commission for Latin America and the Caribbean (ECLAC) were used as main bibliographic axis. Such texts are: Introduction to Keynes, The Economic Development of Latin America and Its Principal Problems, Economic development or monetary stability: the false dilemma, Towards a Dynamic Development Policy for Latin America, .Change and Development: Latin America's Great Task, Capitalismo periférico: crisis y transformación, Five stages in my thinking on development. Firstly the topics essential to economic development according to the author will be exposed, such as industrialization of peripheral countries as a means of raising the income of masses and the way it should be coordinated beyond the theoretical author's choice on historical events, the evolution of the deterioration of terms of trade between peripheral and central countries and the need for productivity gains to increase the income of the worker. Afterwards it will be exposed how such terms align with social inequalities and which definitions are incorporated by the author on the subject
