Cubic twistorial string field theory
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 ...
Degree theory for the sum of VMO maps and maximal monotone maps
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2011)
Problemas elípticos superlineares com ressonância
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em MatemáticaCâmpus 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 ...
On existence of periodic solutions for Kepler type problems
(Juliusz Schauder Ctr Nonlinear Studies, 2016-12)
We prove existence and multiplicity of periodic motions for the forced $2$-body problem under conditions of topological character. In different cases, the lower bounds obtained for the number of solutions are related to ...
Averaging Theory For Discontinuous Piecewise Differential Systems

The g-theorem and quantum information theory
We study boundary renormalization group flows between boundary conformal field theories in 1 + 1 dimensions using methods of quantum information theory. We define an entropic g-function for theories with impurities in terms ...
THE INTEGRAL TRACE FORM OF CYCLIC EXTENSIONS OF ODD PRIME DEGREE
(Rocky Mt Math Consortium, 2017-01-01)
Let L/Q be a cyclic extension of degree p, where p is an odd unramified prime in L/Q. An explicit description of the integral trace form Tr-L/Q(x(2))|O-L, where O-L is the ring of algebraic integers of L, is given, and an ...
