Three-dimensional gravity from the Turaev-Viro invariant [PDF]

open access: yesPhysical Review Letters, 1992
Summary: We study the \(q\)-deformed su(2) spin network as a three-dimensional quantum gravity model. We show that in the semiclassical continuum limit the Turaev-Viro invariant obtained recently defines a naturally regularized path integral a la Ponzano and Regge, in which a contribution from the cosmological term is effectively included.

Skein theory and Turaev-Viro invariants

open access: yesTopology, 1995
Using the so-called chain mail the author identifies two sets of quantum 3-manifold invariants. These were defined by Reshetikin-Turaev respectively Turaev-Viro using different presentations of 3-manifolds and also different quantum initial data. This identification was first done by Walker and Turaev using more complicated methods.

3-Dimensional Gravity and the Turaev-Viro Invariant [PDF]

open access: yesProgress of Theoretical Physics Supplement, 1992
We derived an asymptotic formula for q-6j symbol. This is a generalization of the former work by Ponzano and Regge. Studying the q-deformed su(2) spin network as a 3-dimensional quantum gravity model, we show that the Turaev-Viro invariant defines naturally regularized path-integral a la Ponzano-Regge in the semi-classical continuum limit.

The Turaev-Viro Invariants

2003
These invariants were first described by V. Turaev and 0. Viro [121]. They possess two important properties. First, just like homology groups, they are easy to calculate. Only the limitations of the computer at hand may cause some difficulties. Second, they are very powerful, especially if used together with the first homology group.

GRAPHICAL APPROACH TO THE 3-MANIFOLD INVARIANTS OF TURAEV-VIRO

Journal of Knot Theory and Its Ramifications, 1992
This paper uses graphical techniques introduced by Kirillov and Reshetikhin to give an alternative approach to the construction of the Turaev-Viro invariants for links in \(S^ 3 \) and for closed 3- manifolds. The invariant is defined in terms of a regular diagram for the link (or for a framed link representing the manifold) and is shown to be ...

Which lens spaces are distinguished by Turaev-Viro invariants

Mathematical Notes, 1997
Using the works of \textit{S. Yamada} [J. Knot Theory Ramifications 4, No. 2, 319-327 (1995; Zbl 0843.57004)] and \textit{L. C. Jeffrey} [Commun. Math. Phys. 147, No. 3, 563-604 (1992; Zbl 0755.53054)], the author gives an explicit formula for the value of the Turaev-Viro invariants of the 3-dimensional lens spaces \(L_{p,q}\).

Possible universal quantum algorithms for generalized Turaev-Viro invariants

Proceedings of SPIE, 2011
An emergent trend in quantum computation is the topological quantum computation (TQC). Briefly, TQC results from the application of quantum computation with the aim to solve the problems of quantum topology such as topological invariants for knots and links (Jones polynomials, HOMFLY polynomials, Khovanov polynomials); topological invariants for ...
