Move-by-move dynamics of the advantage in chess matches reveals population-level learning of the game
H. V. Ribeiro, R. S. Mendes, E. K. Lenzi +2
The complexity of chess matches has attracted broad interest since its invention. This complexity and the availability of large number of recorded matches make chess an ideal model…
Stabilization of regular solutions for the Zakharov-Kuznetsov equation posed on bounded rectangles and on a strip
G. G. Doronin, N. A. Larkin
Initial-boundary value problems for the 2D Zakharov-Kuznetsov equation posed on bounded rectangles and on a strip are considered. Spectral properties of a linearized operator and c…
The Analytic Classification of Plane Curves with Two Branches
Abramo Hefez, Marcelo Escudeiro Hernandes, Maria Elenice Rodrigues Hernandes
In this paper we solve the problem of analytic classification of plane curves singularities with two branches by presenting their normal forms. This is accomplished by means of a n…
Anomalous Diffusion and Long-range Correlations in the Score Evolution of the Game of Cricket
H. V. Ribeiro, Satyam Mukherjee, Xiao Han T. Zeng
We investigate the time evolution of the scores of the second most popular sport in world: the game of cricket. By analyzing the scores event-by-event of more than two thousand mat…
Invariants and relative invariants under compact Lie groups
Patricia H. Baptistelli, Miriam Manoel
This paper presents algebraic methods for the study of polynomial relative invariants, when the group G formed by the symmetries and relative symmetries is a compact Lie group. We…
Complexity-Entropy Causality Plane as a Complexity Measure for Two-dimensional Patterns
H. V. Ribeiro, L. Zunino, E. K. Lenzi +2
Complexity measures are essential to understand complex systems and there are numerous definitions to analyze one-dimensional data. However, extensions of these approaches to two o…
