چکیده
Integral of a certain multivalued form over cycle ∆ provides zonal spherical function of type An. This paper is devoted to quantum group analysis and verification of monodromy properties of the distinguished cycle ∆. Zonal spherical function is a particular conformal block of WAn-algebra 0.0 Notations. α1, α2, . . . , αn simple roots of root system of type An R+ set of positive roots R root system of type An δ = 1 2 ∑ α∈R+ α -halfsum of positive roots kcomplex parameter ( ‘halfmultiplicity’ of a root)

HARISH-CHANDRA DECOMPOSITION FOR ZONAL SPHERICAL FUNCTION OF TYPE An A. Kazarnovski-Krol
Heckman-Opdam system of differential equations is holonomic , with regular singularities and has locally |W |-dimensional space of solutions ( cf. corollary 3.9 of [12]), where |W | is the cardinality of the Weyl group W . The system is a generalization of radial parts of Laplace-Casimir operators on symmetric Riemannian spaces of nonpositive curvature and is isomorphic to Calogero-Sutherland m...

In this study the third order nonlinear susceptibilities are theoreticallycalculated for an electron confined in an isolated PbS/ CdSe/ CdS spherical core-shellshellquantum dots. Our calculation is associated with intersubband transitions in theconduction band. We used the effective mass approximation in this study which is asimple and straightforward study of the third-order optical nonlineari...
متن کاملO N the Numerical Integration of the Primitive of Motion for Baroclinic Flow in a Closed Equations Region
This paper considers the problem of numerically integrating the primitive equations corresponding to B 2-level model of the atmosphere bounded by two zonal walls on a spherical earth. Inertio-gravitational motions of the external type are filtered a priori; for such a constraint it is possible to define a stream function corresponding to the vertically integrated motions. A system of integratio...
متن کاملTHE EFFECT OF TYPE OF SPECIFIC HEATS RATIO OF WORKING FLUID ON THE THERMAL PERFORMANCE OF STANDARD OTTO CYCLE
In thermodynamic analysis of internal combustion engine, the specific heats of working fluid is considered to be constant. Due to specific heats are functions of operation temperature of cycle, this consideration cause to several errors in the thermal analysis. In this paper, standard Otto cycle with three various types of specific heats ratios has been analyzed numerically and effect of these ...
