Boundedly Spaced Subsequences and Weak Dynamics
C. S. Kubrusly, P. C. M. Vieira
The purpose of this paper is to characterize weak supercyclicity for Hilbert-space contractions, which is shown to be equivalent to characterizing weak supercyclicity for unitary o…
Emergence of complex data from simple local rules in a network game
Felipe S. Abrahão, Klaus Wehmuth, Artur Ziviani
As one of the main subjects of investigation in data science, network science has been demonstrated a wide range of applications to real-world networks analysis and modeling. For e…
An optimal convergence analysis of the hybrid Raviart-Thomas mixed discontinuous Galerkin method for the Helmholtz equation
Jiansong Zhang, Jiang Zhu
The hybrid Raviart-Thomas mixed discontinuous Galerkin (HRTMDG) method is proposed for solving the Helmholtz equation. With a new energy norm, we establish the existence and unique…
On the existence of hidden machines in computational time hierarchies
Felipe S. Abrahão, Klaus Wehmuth, Artur Ziviani
Challenging the standard notion of totality in computable functions, one has that, given any sufficiently expressive formal axiomatic system, there are total functions that, althou…
On the full-waveform inversion of seismic moment tensors
Alan A. S. Amad, Antonio A. Novotny, Bojan B. Guzina
In this work, we propose a full-waveform technique for the spatial reconstruction and characterization of (micro-) seismic events via joint source location and moment tensor invers…
Applying Lie Groups Approaches for Rigid Registration of Point Clouds
Liliane Rodrigues de Almeida, Gilson A. Giraldi, Marcelo Bernardes Vieira
In the last decades, some literature appeared using the Lie groups theory to solve problems in computer vision. On the other hand, Lie algebraic representations of the transformati…
