Quark mass function from a one-gluon-exchange-type interaction in Minkowski space
Elmar P. Biernat, Franz Gross, M. T Peña +2
We present first results for the quark mass function in Minkowski space in both the spacelike and timelike regions calculated from the same quark-antiquark interaction kernel used…
Minkowski identities for hypersurfaces in constant sectional curvature manifolds
R. Albuquerque
We give a new proof of the generalized Minkowski identities relating the higher degree mean curvatures of orientable closed hypersurfaces immersed in a given constant sectional cur…
Symmetric Decomposition of the Associated Graded Algebra of an Artinian Gorenstein Algebra
Anthony Iarrobino, Pedro Macias Marques
We study the symmetric subquotient decomposition of the associated graded algebras of a non-homogeneous commutative Artinian Gorenstein (AG) algebra . This decomposition a…
Skew-Symmetric Tensor Decomposition
Enrique Arrondo, Alessandra Bernardi, Pedro Macias Marques +1
We introduce the ``skew apolarity lemma'' and we use it to give algorithms for the skew-symmetric rank and the decompositions of tensors in { with $d\leq…
Notes on the Sasaki metric
Rui Albuquerque
We survey on the geometry of the tangent bundle of a Riemannian manifold, endowed with the classical metric established by S. Sasaki 60 years ago. Following the results of Sasaki,…
Deep XMM-Newton observations of the northern disc of M31. I. Source catalogue
M. Sasaki, F. Haberl, M. Henze +12
We carried out new observations of two fields in the northern ring of M31 with XMM-Newton with two exposures of 100 ks each and obtained a complete list of X-ray sources down to a…
