Parallelisation of Discrete Exterior Calculus via Representation Theory on Curved and Three-Dimensional Meshes
Leon D. da Silva, Marcelo P. Santos, José D. da Silva +1
We establish a universal block-diagonalization framework for Discrete Exterior Calculus (DEC) operators on symmetric meshes, enabling embarrassingly parallel solvers with provable…

Curves and surfaces making a constant angle with a parallel transported direction in Riemannian spaces
Luiz C. B. da Silva, Gilson S. Ferreira, José D. da Silva
In the last two decades, much effort has been dedicated to studying curves and surfaces according to their angle with a given direction. However, most findings were obtained using…

Curves orthogonal to a vector field in Euclidean spaces
Luiz C. B. da Silva, Gilson S. Ferreira
A curve is rectifying if it lies on a moving hyperplane orthogonal to its curvature vector. In this work, we extend the main result of [Chen 2017, Tamkang J. Math. 48, 209] to any…
