Stable Liftings of Polynomial Traces on Tetrahedra
Charles Parker, Endre Süli
On the reference tetrahedron , we construct, for each , a right inverse for the trace operator $u \mapsto (u, \partial_{n} u, \ldots, \partial_{n}^k u)|_{\pa…
Photon-triggered jets as probes of multi-stage jet modification
C. Sirimanna, Y. Tachibana, A. Angerami +50
Prompt photons are created in the early stages of heavy ion collisions and traverse the QGP medium without any interaction. Therefore, photon-triggered jets can be used to study th…
Measuring jet quenching with a Bayesian inference analysis of hadron and jet data by JETSCAPE
R. Ehlers, A. Angerami, R. Arora +50
The JETSCAPE Collaboration reports the first multi-messenger study of the QGP jet transport parameter using Bayesian inference, incorporating all available hadron and jet…
Computing -conforming finite element approximations without having to implement -elements
Mark Ainsworth, Charles Parker
We develop a method to compute the -conforming finite element approximation to planar fourth order elliptic problems without having to implement elements. The algorithm…
Stable Lifting of Polynomial Traces on Triangles
Charles Parker, Endre Süli
We construct a right inverse of the trace operator on the reference triangle that maps suitable piecewise polynomial d…
Uniform Preconditioners for High Order Finite Element Approximations of Planar Linear Elasticity
Mark Ainsworth, Charles Parker
A new preconditioner is developed for high order finite element approximation of linear elastic problems on triangular meshes in two dimensions. The new preconditioner results in a…
