Cubic twistorial string field theory
(2004-04-01)
Witten has recently proposed a string theory in twistor space whose D-instanton contributions are conjectured to compute M = 4 super-Yang-Mills scattering amplitudes. An alternative string theory in twistor space was then ...

Applications of topological degree theory to generalized ODEs
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2019-10-27)
In this work, we present original results concerning the theory of Generalized Ordinary Differential Equations (we write generalized ODEs for short) using tools from the Topological Degree theory. In particular, we proved ...
Topological methods for a nonlinear elliptic system with nonlinear boundary conditions
(Inderscience Publishers, 2009-09)
A nonlinear elliptic second order system with a nonlinear boundary condition is studied. We prove an existence result under a Hartman type condition. Moreover, assuming appropriate conditions of Nirenberg type, we prove ...
Problemas elípticos superlineares com ressonância
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2015-08-14)
The aim of this work is to present results about the existence of non-trivial solutions for some classes of resonant and superlinear eliptic systems employing topological methods. More specifcally, we use a-priori bounds ...
O mistério por trás da resolução de equações polinomiais
(Universidade Tecnológica Federal do ParanáToledoBrasilLicenciatura em MatemáticaUTFPR, 2021-08-03)
Solving polynomial equations was a problem that followed countless mathematicians over the centuries. As mathematics improved, formulas for Ąnding polynomial roots were developed. But the great mystery that plagued the ...
