A Clifford algebra gauge invariant Lagrangian for gravity. Part 2 : compatibility with General Relativity tests

Inspired by recent results relating the Racah algebra and the centralizers of su (2) [4], we have found an explicit isomorphism (that we report here) between a quotient of

We then show how by plugging a pure gauge field in the gauge fixing equation, thus inspecting the residual gauge freedom, one gets, as a byproduct, a conformally invariant equation

The first paragraph is related to an interpolation method called B-splines which is commonly used in semi-Lagrangian methods and known to be less diffusive than classical

This note provides a detailed computation of the Ext-algebra for a very specific finite dimensional algebra, namely a Brauer tree algebra associated to a line, with no

In the work, we investigate boundary stabilization of a class of linear first-order hyperbolic systems of Partial Differential Equations (PDEs) on a finite space domain x ∈ [0, 1]..
