Anticommutativity of Skew-symmetric Elements under Generalized Oriented Involutions
Edward Landi Tonucci, Thierry Corrêa Petit Lobão
Let be a ring with whose unit group are denoted by , a group, and its group ring. Let be an involution in , $σ:G\rightarrow\mathc…
Non-distributive algebraic structures derived from nonextensive statistical mechanics
Pedro G. S. Cardoso, Ernesto P. Borges, Thierry C. P. Lobão +1
We propose a two-parametric non-distributive algebraic structure that follows from -logarithm and -exponential functions. Properties of generalized -operato…
Characterization of complex networks by higher order neighborhood properties
Roberto F. S. Andrade, José G. V. Miranda, Suani T. R. Pinho +1
A concept of higher order neighborhood in complex networks, introduced previously (PRE \textbf{73}, 046101, (2006)), is systematically explored to investigate larger scale structur…
Neighborhood properties of complex networks
R. F. S. Andrade, J. G. V. Miranda, Thierry Petit Lobao
A concept of neighborhood in complex networks is addressed based on the criterion of the minimal number os steps to reach other vertices. This amounts to, starting from a given net…
The network of concepts in written texts
Silvia M. G. Caldeira, Thierry C. Petit Lobao, R. F. S. Andrade +2
Complex network theory is used to investigate the structure of meaningful concepts in written texts of individual authors. Networks have been constructed after a two phase filterin…
