Semibounded representations and invariant cones in infinite dimensional Lie algebras [PDF]

open access: yes, 2009
A unitary representation of a, possibly infinite dimensional, Lie group $G$ is called semi-bounded if the corresponding operators $i\dd\pi(x)$ from the derived representations are uniformly bounded from above on some non-empty open subset of the Lie ...

Cooking pasta with Lie groups

open access: yesNuclear Physics B, 2022
We extend the (gauged) Skyrme model to the case in which the global isospin group (which usually is taken to be SU(N)) is a generic compact connected Lie group G.

The moment map of a Lie group representation [PDF]

open access: yesTransactions of the American Mathematical Society, 1992
Given an m × m m \times m Hadamard matrix one can extract m 2 {m^2} symmetric designs on m − 1 m - 1 points each of which extends uniquely to a 3 3 -design.

An Invitation to Higher Gauge Theory [PDF]

open access: yes, 2010
In this easy introduction to higher gauge theory, we describe parallel transport for particles and strings in terms of 2-connections on 2-bundles. Just as ordinary gauge theory involves a gauge group, this generalization involves a gauge '2-group'.

Yang-Yang functions, monodromy and knot polynomials

open access: yesJournal of High Energy Physics, 2021
We derive a structure of ℤ[t, t −1]-module bundle from a family of Yang-Yang functions. For the fundamental representation of the complex simple Lie algebra of classical type, we give explicit wall-crossing formula and prove that the monodromy ...

On the extensions of infinite-dimensional representations of Lie semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
The necessary and sufficient conditions have been obtained for extendability of a Banach representation of a generating Lie semigroup S to a local representation of the Lie group G generated by S when the tangent wedge of S is a Lie semialgebra. The most

Equivariant K‐theory of compact Lie group actions with maximal rank isotropy [PDF]

open access: yesJournal of Mathematics and Physics, 2012
Let G denote a compact connected Lie group with torsion‐free fundamental group acting on a compact space X such that all the isotropy subgroups are connected subgroups of maximal rank. Let T⊂G be a maximal torus with Weyl group W.

Symmetry Representations in the Rigged Hilbert Space Formulation of Quantum Mechanics [PDF]

open access: yes, 2002
We discuss some basic properties of Lie group representations in rigged Hilbert spaces. In particular, we show that a differentiable representation in a rigged Hilbert space may be obtained as the projective limit of a family of continuous ...

Haar expectations of ratios of random characteristic polynomials [PDF]

open access: yes, 2016
We compute Haar ensemble averages of ratios of random characteristic polynomials for the classical Lie groups K = O(N), SO(N), and USp(N). To that end, we start from the Clifford-Weyl algebera in its canonical realization on the complex of holomorphic ...

Lie Supergroups Obtained from 3-Dimensional Lie Superalgebras Associated to the Adjoint Representation and Having a 2-Dimensional Derived Ideal

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
We give the explicit multiplication law of the Lie supergroups for which the base manifold is a 3-dimensional Lie group and whose underlying Lie superalgebra g=g0⊕g1 which satisfies g1=g0, g0 acts on g1 via the adjoint representation and g0 has a 2 ...
