A polynomial Jacobi-Davidson solver with support for non-monomial bases and deflation

Campos, Carmen; Jose E. Roman (Springer-Verlag, 2020-06)

[EN] Large-scale polynomial eigenvalue problems can be solved by Krylov methods operating on an equivalent linear eigenproblem (linearization) of size d center dot n where d is the polynomial degree and n is the problem ...
Computation of scattering resonances in absorptive and dispersive media with applications to metal-dielectric nano-structures

Araujo C., Juan C.; Campos, Carmen; Engstrom, Christian; Roman, Jose E. (Elsevier, 2020-04-15)

[EN] In this paper we consider scattering resonance computations in optics when the resonators consist of frequency dependent and lossy materials, such as metals at optical frequencies. The proposed computational approach ...
Estudio de la influencia de la red de interconexión en la ejecución de aplicaciones paralelas

Campos González, María Camen (Universitat Politècnica de València, 2011-01-10)
Extensión de la librería SLEPc para el cálculo de todos los valores propios contenidos en un intervalo en problemas simétricos

Campos González, María Carmen (Universitat Politècnica de València, 2013-03-10)

[ES] En el contexto de problemas de valores propios generalizados simétricos definidos, frecuentemente es necesario calcular todos los autovalores contenidos en un intervalo dado. En problemas de gran escala, el método ...
Implementación paralela de métodos iterativos para la resolución de problemas polinómicos de valores propios

Campos González, María Carmen (Universitat Politècnica de València, 2017-09-01)

The polynomial eigenvalue problem appears in many areas of scientific and technical computing. It can be seen as a generalization of the linear eigenvalue problem in which the equation P(lambda)x = 0, that defines the ...
Improvements to SLEPc in releases 3.14-3.18

Jose E. Roman; Alvarruiz Bermejo, Fernando; Campos, Carmen; Dalcin, Lisandro; Jolivet, Pierre; Lamas Daviña, Alejandro (Association for Computing Machinery, 2023-09)

[EN] This short article describes the main newfeatures added to SLEPc, the Scalable Library for Eigenvalue Problem Computations, in the past two and a half years, corresponding to five release versions. The main novelty ...
Inertia-based spectrum slicing for symmetric quadratic eigenvalue problems

Campos, Carmen; Román Moltó, José Enrique (John Wiley & Sons, 2020-08)

[EN] In the quadratic eigenvalue problem (QEP) with all coefficient matrices symmetric, there can be complex eigenvalues. However, some applications need to compute real eigenvalues only. We propose a Lanczos-based method ...
NEP: A Module for the Parallel Solution of Nonlinear Eigenvalue Problems in SLEPc

Campos, Carmen; Roman, Jose E. (Association for Computing Machinery, 2021-06)

[EN] SLEPc is a parallel library for the solution of various types of large-scale eigenvalue problems. Over the past few years, we have been developing a module within SLEPc, called NEP, that is intended for solving nonlinear ...
Non-linear eigenvalue problems with GetDP and SLEPc: Eigenmode computations of frequency-dispersive photonic open structures

Demesy, Guillaume; Nicolet, André; Gralak, Boris; Geuzaine, Christophe; Campos, Carmen; Roman, Jose E. (Elsevier, 2020-12)

[EN] We present a framework to solve non-linear eigenvalue problems suitable for a Finite Element discretization. The implementation is based on the open-source finite element software GetDP and the open-source library ...
Solving symmetric quadratic eigenvalue problems with SLEPc

Román Moltó, José Enrique; Campos González, Maria Camen (European Mathematical Society, 2013)
Strategies for spectrum slicing based on restarted Lanczos methods

Campos González, Maria Camen; Román Moltó, José Enrique (Springer Verlag (Germany), 2012-06)

In the context of symmetric-definite generalized eigenvalue problems, it is often required to compute all eigenvalues contained in a prescribed interval. For large-scale problems, the method of choice is the so-called ...
Thick-restarted joint Lanczos bidiagonalization for the GSVD

Alvarruiz Bermejo, Fernando; Campos, Carmen; Roman, Jose E. (Elsevier, 2024-04)

[EN] The computation of the partial generalized singular value decomposition (GSVD) of large-scale matrix pairs can be approached by means of iterative methods based on expanding subspaces, particularly Krylov subspaces. ...
