... Take a piece of graph paper with 1-cm squares, preferably also with 1-mm small squares, and draw the vectors starting from a point near the center of the graph paper, which we will call the origin (0,0). It always makes sense to choose the vertical and horizontal scales according to a ‘‘simple-to-us ...

PARADIGM OF QUASI-LIE AND QUASI-HOM

... hom-Lie and quasi-hom-Lie algebras associated to discrete analogues of vector fields built via twisted derivations. We also demonstrate application of the method to sl2 (F) resulting in parametric families of algebras, the quasi-hom-Lie and hom-Lie quasi-deformations of sl2 (F), considered in [29]. ...

... Multiplying a vector, v by a scalar, k, creates a new vector with the magnitude k times as large. The direction of the vector does not change unless the scalar is negative which would then make the new direction opposite to the original. Multiplying by zero creates a vector of magnitude 0. ...

And a function that is linear in density operators becomes non linear when translated into spinor language. This means that some problems that are simple in one of these formalisms will becom ...

Generation of Clebsch–Gordan coefficients for the point and double

... In recent years, a large number of studies have been carried out to understand the spectra of atoms which are placed in a potential of lower than spherical symmetry [1–3]. Such a potential occurs for instance for atoms in a crystal field. In order to explore the structure of atoms, incorporated into ...

... This projection is a fibration with fiber π −1 (z) = Yz . We define a vector bundle H1twist (Y /X) over X whose fiber at z is the twisted homology group H1twist (Yz ). An element Cz0 ∈ H1twist (Yz0 ) naturally defines a twisted cycle in every fiber H1twist (Yz ) if z is sufficiently close to z0 . Such local ...

... The main advantage of this approach is that this expansion includes further anharmonic terms with (e.g.) three or four magnon operators. Such terms are necessary to set up the kinetic theory of magnons, since they tell the magnon-magnon scattering or spontaneous decay of magnons. Anharmonic terms al ...
