• Noncommutative description of spin hall effect 

  Jellal A.; Houca R. (SINGAPORE5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE, 2009)

  We propose an approach based on a generalized quantum mechanics to deal with the basic features of the intrinsic spin Hall effect. This can be done by considering two decoupled harmonic oscillators on the noncommutative ...
• Construction of vector-valued modular integrals and vector-valued mock modular forms 

  Gimenez J.; Muhlenbruch T.; Raji W. (Kluwer Academic Publishers;, 2014)

  It is known that, given a vector-valued modular form of negative weight, its Fourier coefficients can be calculated based on the principal part of the form. In this paper we start with an arbitrary principal part and ...

• Quantum hall effect on the flag manifold F2 

  Daoud M.; Jellal A. (SINGAPORE5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE, 2008)

  The Landau problem on the flag manifold F2 = SU(3)-U(1)×U(1) is analyzed from an algebraic point of view. The involved magnetic background is induced by two U(1) Abelian connections. In quantizing the theory, we show that ...

• Meromorphic functions compatible with homomorphisms of actions on C 

  Maalouf R.N.; Raji W. (, 2012)

  We consider homomorphisms H : G1 → G2 of holomorphic (group or pseudogroup) actions G1 and G2 on domains Ω1 and Ω2 respectively in C, together with meromorphic functions f that are compatible with these homomorphisms in ...
• Gorenstein hilbert coefficients 

  Khoury S.E.; Srinivasan H. (TEMPEARIZ STATE UNIV, DEPT MATH, TEMPE, AZ 85287-1904 USA, 2013)

  We prove upper and lower bounds for all the coefficients in the Hilbert polynomial of a graded Gorenstein algebra S = R-I with a quasi-pure resolution over R. The bounds are in terms of the minimal and the maximal shifts ...
• Weighted isoperimetric inequalities in cones and applications 

  Brock F.; Chiacchio F.; Mercaldo A. (OXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2012)

  This paper deals with weighted isoperimetric inequalities relative to cones of RN. We study the structure of measures that admit as isoperimetric sets the intersection of a cone with balls centered at the vertex of the ...
• Generalized maass wave forms 

  Muhlenbruch T.; Raji W. (PROVIDENCE201 CHARLES ST, PROVIDENCE, RI 02940-2213 USA, 2013)

  We initiate the study of generalized Maass wave forms, those Maass wave forms for which the multiplier system is not necessarily unitary. We then prove some basic theorems inherited from the classical theory of modular ...
• Central schemes on unstructured grids 

  Touma R.; Jannoun G. (, 2012)

  In this paper we present a two-dimensional extension of the staggered Lax-Friedrichs scheme for the approximate solution of hyperbolic conservation laws on unstructured grids. By evolving the numerical solution on two ...
• The tree model of a meromorphic plane curve 

  Assi A. (Real Acadademia de Ciencias; MILANVIA DECEMBRIO, 28, MILAN, 20137, ITALY, 2014)

  We associate with a plane meromorphic curve f a tree model T(f) based on its contact structure. Then we give a description of the y-derivative of f (resp. the Jacobian J(f, g)) in terms of T(f) (resp. T(f, g)). We also ...

  Bergman G.M.; Nahlus N. (SAN DIEGO525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA, 2012)

  Let k be an infinite field, I an infinite set, V a k-vector-space, and g : k I → V a k-linear map. It is shown that if dim k(V) is not too large (under various hypotheses on card(k) and card(I), if it is finite, respectively ...
