Reduction of Algebraic Parametric Systems by Rectification of Their Affine Expanded Lie Symmetries
Lie group theory states that knowledge of a m-parameters solvable group of symmetries of a system of ordinary differential equations allows to reduce by m the number of equations. ...

Optimal Control and Geodesics on Quadratic Matrix Lie Groups
In this paper, we consider some matrix subgroups of the general linear group and in particular the special linear group that are defined by a quadratic matrix identity. The Lie al...

Computable Obstructions to Wait-free Computability
Abstract. We show how to associate e ectively computableobstructions to a waitfree distributed decision task (I;O; ) in the asynchronous shared-memory, readwrite model. The key new...
