SUSY structures, representations and Peter-Weyl theorem for
The real compact supergroup is analized from different perspectives
and its representation theory is studied. We prove it is the only (up to
isomorphism) supergroup, which is a real form of
with reduced Lie group , and a link with SUSY structures on is established. We describe a large family of complex semisimple
representations of and we show that any -representation
whose weights are all nonzero is a direct sum of members of our family. We also
compute the matrix elements of the members of this family and we give a proof
of the Peter-Weyl theorem for
Compact forms of Complex Lie Supergroups
In this paper we construct compact forms associated with a complex Lie
supergroup with Lie superalgebra of classical type
Smoothness of Algebraic Supervarieties and Supergroups
In this paper we discuss the notion of smoothness in complex algebraic
supergeometry and we prove that all affine complex algebraic supergroups are
smooth. We then prove the stabilizer theorem in the algebraic context,
providing some useful applications
A Comparison between Star Products on Regular Orbits of Compact Lie Groups
In this paper an algebraic star product and differential one defined on a
regular coadjoint orbit of a compact semisimple group are compared. It is
proven that there is an injective algebra homomorphism between the algebra of
polynomials with the algebraic star product and the algebra of differential
functions with the differential star product structure.Comment: AMS-LaTeX, 19 pages. Version to appear in the Journal of Physics
