Wreath Product Symmetric Functions

We systematically study wreath product Schur functions and give a combinatorial construction using colored partitions and tableaux. The Pieri rule and the Littlewood-Richardson rule are studied. We also discuss the connection with representations of generalized symmetric groups.

Orbifold Cohomology of a Wreath Product Orbifold

Abstract. Let [X/G] be an orbifold which is a global quotient of a compact almost complex manifold X by a finite group G. Let Σn be the symmetric group on n letters. Their semidirect product G ⋊ Σn is called the wreath product of G and it naturally acts on the n-fold product X, yielding the orbifold [X/(G ⋊Σn)]. Let H (X , G ⋊Σn) be the stringy cohomology [FG, JKK1] of the (G ⋊ Σn)-space X . Wh...

Wreath product cyclic group-based convolution: a new class of noncommutative filters

The theory of spectral analysis of a particular class of non-commutative groups|wreath products of cyclic groups| has been shown to have a group-based convolution that leads to a new class of noncommutative lters. These lters, with their group and scale-selective properties and their relationship to DFT lter banks, ooer some intriguing possibilities in signal processing applications. In this pa...
