Quadratic systems with invariant straight lines of total multiplicity two having Darboux invariants
(World ScientificSingapore, 2015)
In this paper, we present the global phase portraits in the Poincaré disc of the planar quadratic polynomial systems which admit invariant straight lines with total multiplicity two and Darboux invariants.
On the spectral analysis of residual stress in finite elasticity
(Oxford university press, 2017)
In the literature, residual stress problems are generally formulated using classical invariants despite most of them having an unclear physical meaning and not having experimental advantages. In this article, we give an ...

Invariance of a shift-invariant space
(Birkhauser Boston Inc, 2010-01)
A shift-invariant space is a space of functions that is invariant under integer translations. Such spaces are often used as models for spaces of signals and images in mathematical and engineering applications. This paper ...

Invariants de Maslov équivariants
(2002-03)
We construct two cohomological invariants associated to pairs of Lagrangian sub-bundles of a symplectic bundle on a compact manifold upon which a compact Lie group is acting. The first invariant, which we call the classical ...
