Four-Dimensional Spin Foam Perturbation Theory
Published 2011-10-01“…We then regularize the terms in the perturbative series by passing to the category of representations of the quantum group U_q(g) where g is the Lie algebra of G and q is a root of unity. The Chain-Mail formalism can be used to calculate the perturbative terms when the vector space of intertwiners Λ⊗Λ→A, where A is the adjoint representation of g, is 1-dimensional for each irrep Λ. …”

Γ-invariant ideals in Iwasawa algebras
Published 2009“…The minimal codimension of these subspaces gives a lower bound on the homological height of I in terms of the action of a certain Lie algebra on G / Gp. If we take Γ to be G acting on itself by conjugation, then Γ-invariant right ideals of k G are precisely the two-sided ideals of k G, and we obtain a non-trivial lower bound on the homological height of a possible non-zero two-sided ideal. …”

Modeling of entangled states in qubit clusters
Published 2022-12-01“…It turns out that the approach based on the representation of Hamiltonians and unitary transformations in the Pauli basis is the most suitable in this context for two reasons: firstly, the Pauli basis forms the Lie algebra of the corresponding unitary group; secondly, there are only real coefficients in the decompositions of Hamiltonians and state density operators in this basis. …”
