The Ptolemy coordinates for boundary-unipotent SL(n; C)-representations of a
3-manifold group were introduced in [7] inspired by the A-coordinates on higher Teichmuller
space due to Fock and Goncha...

positive de nite functions.
De nition. A continuous function f : R ! C is called positive de nite if

Fenchel-Nielsen Coordinates for Maximal Representations
Fenchel-Nielsen Coordinates Maximal Representations
2012/4/23
We develop Fenchel-Nielsen coordinates for representations of surface groups into Sp(2n,R) with maximal Toledo invariant. Analogous to classical Fenchel-Nielsen coordinates on the Teichm\"uller space ...
Lie algebroid modules and representations up to homotopy
Lie algebroid representation up to homotopy graded manifold graded vector bundle Q-manifold
2011/8/30
Abstract: We explain how Lie algebroid modules in the sense of Vaintrob provide geometric models for Lie algebroid representations up to homotopy. Specifically, we show that there is a noncanonical wa...
Tensorial representations of Reynolds-stress redistribution
Tensorial representations Reynolds-stress redistribution

The purpose of the present note is to contribute in clarifying the relation between representation bases used in the closure for the redistribution (pressure-strain) tensor fi j , and to propose a rep...
Geometric approach to Hall algebra of representations of Quivers over local ring
Quantum generalized Kac-Moody algebra Hall algebra quiver local ring
2011/2/25
The category of representations of a Dynkin quiver over local ring R = k[t]/(tn) is not hereditary any more. The Hall algebra defined on this category doesn’t have a well defined coalgebraic structure...
Integrable defects in affine Toda field theory and infinite dimensional representations of quantum groups
Integrable defects affine Toda field theory infinite dimensional representations quantum groups

Transmission matrices for two types of integrable defect are calculated explicitly, first by solving directly the nonlinear transmission Yang-Baxter equations.
Geometrization of principal series representations of GL_N associated to regular characters
Geometrization principal series representations
2010/11/23
In geometric representation theory, one often wishes to describe representations realized on spaces of invariant functions as trace functions of equivariant perverse sheaves. In the case of principal...
Representations of multidimensional linear process bridges
multidimensional linear process bridges math
2010/11/8
We derive bridges from general multidimensional linear non time-homogeneous processes using only the transition densities of the original process giving their integral representations (in terms of a s...
Tensor products of representations up to homotopy
Tensor products of representations homotopy
2010/12/14
We study the construction of tensor products of representations up to homotopy, which
are the A∞ version of ordinary representations. We provide formulas for the construction
of tensor products of r...
Representations of Affine and Toroidal Lie Algebras
Representations of Affine Toroidal Lie Algebras
2010/12/1
We discuss the category I of level zero integrable representations of loop algebras and their generalizations. The category is not semisimple and so one is interested in its homological properties.
Groups with faithful irreducible projective unitary representations
Projective unitary representations irreducible representations
2010/12/10
For a countable group and a multiplier ∈ Z2(,T),we study the property of having a unitary projective -representation which is both irreducible and projectively faith...
