A Schwarz Method for the Magnetotelluric Approximation of Maxwell's equations
Fabrizio Donzelli, Martin J. Gander, Ronald D. Haynes
The magnetotelluric approximation of the Maxwell's equations is used to model the propagation of low frequency electro-magnetic waves in the Earth's subsurface, with the purpose of…
Massively parallel stochastic solution of the geophysical gravity problem
Fabrizio Donzelli, Alexander Bihlo, Mauricio Kischinhevsky +1
In this paper, we report the advantages of using a stochastic algorithm in the context of mineral exploration based on gravity measurements. This approach has the advantage over de…
Lie algebras of zero divergence vector fields on complex affine algebraic varieties
Fabrizio Donzelli
For a smooth manifold equipped with a volume form, let $\dL$ be the Lie algebra of volume preserving smooth vector fields on . A. Lichnerowicz proved that the abelianization…
Makar-Limanov invariant, Derksen invariant, flexible points
Fabrizio Donzelli
We estabilish some connections among the Makar-Limanov invariant, the Derksen invariant, and the existence of flexible points on an affine variety.
Algebraic density property of Danilov-Gizatullin surfaces
Fabrizio Donzelli
A Danilov-Gizatullin surface is an affine surface which is the complement of an ample section of a Hirzebruch surface. The remarkable theorem of Danilov and Gizatullin stat…
Algebraic density property of homogeneous spaces
Fabrizio Donzelli, Alexander Dvorsky, Shulim Kaliman
Let be an affine algebraic variety with a transitive action of the algebraic automorphism group. Suppose that is equipped with several non-degenerate fixed point free $SL_2…
