This is a short (and, so far, incomplete) outline of my curriculum vitæ. My full name is Jorge Lacerda de Lyra, I was born on May 20, 1954, in São Paulo, SP, Brazil, the son of Prof. Carlos Benjamin de Lyra and Mrs. Leda Lacerda de Lyra. I sign my scientific work as Jorge L. deLyra. My father was a professor of Mathematics at the University of São Paulo.

A Few Papers Published in Traditional Media:

These are the few papers that I actually still care about. Most of the scientific work that I have done or that I am still doing is available on the web at this site.

``Differentiability and continuity of quantum fields on a lattice'', J. L. deLyra, T. E. Gallivan and S.-K. Foong, Phys. Rev. D43 (1991) 476-484.
``Finite lattice systems with true critical behavior'', J. L. deLyra, T. E. Gallivan and S.-K. Foong, Phys. Rev. D46 (1992) 1643-1657.
``Symmetry breaking on a finite euclidean lattice'', J. L. deLyra and A. C. R. Martins, Nucl. Phys. B432 (1994) 621-640.

A few work by students I have advised:

These works by my former students contain significant contributions to the research line I am interested in.

Doctoral Thesis by André Cavalcanti Rocha Martins, on October 1996, at the University of São Paulo, in Portuguese: "Um Estudo sobre Quebra de Simetria e Comportamento Crítico em Teorias Quânticas de Campos na Rede" (A Study of Symmetry Breaking and Critical Behavior in Quantum Field Theory on the Lattice).
M.Sc. dissertation by Arnaldo Gomes de Oliveira Filho, on April 1998, in Portuguese: "Configurações Topológicas no Modelo Sigma Não-Linear SO(2)" (Topological Configurations in the SO(2) Non-Linear Sigma Model).
