On Induced Gravity in 2-d Topological Theories

, 1993
We study 2-d $\phi F$ gauge theories with the objective to understand, also at the quantum level, the emergence of induced gravity. The wave functionals - representing the eigenstates of a vanishing flat potential - are obtained in the $\phi ...

A Similarity Metric Method for Contour Line Groups Considering Terrain Features

ISPRS International Journal of Geo-Information
Contour lines, as the primary elements of fundamental geospatial data, have long been a research focus for similarity measurement. With the evolution of cartographic generalization, the representation of contour lines across varying scales must maintain ...

Coţofeni-Kostolac culture on the territory of north-eastern Serbia [PDF]

Starinar, 2012
The settlement of the territory of north-eastern Serbia by the representatives of the Coţofeni culture began during the second half of the IV millennium, probably under the pressure of invading tribes from Euroasian steppe.

Link groups of 4-manifolds

, 2012
The notion of a Bing cell is introduced, and it is used to define invariants, link groups, of 4-manifolds. Bing cells combine some features of both surfaces and 4-dimensional handlebodies, and the link group \lambda(M) measures certain aspects of the ...

Non-Clifford Gates between Stabilizer Codes via Non-Abelian Topological Order

PRX Quantum
We propose protocols to implement non-Clifford logical gates between stabilizer codes by entangling into a non-Abelian topological order as an intermediate step. Generalizing previous approaches, we provide a framework that generates a large class of non-

Metric and Topological Aspects of the Symmetric Group of Countable Degree

European Journal of Combinatorics, 1996
This is a short and elegant survey on the topology on the symmetric group on a countable set. The paper includes some applications of Haar measure, a discussion of cofinitary permutation groups (that is, groups where every non-identity element has just finitely many fixed points), and an infinitary version of ideas of Maillet, with connections with ...

Topological B-Model, Matrix Models, $\hat{c}=1$ Strings and Quiver Gauge Theories

, 2004
We study topological and integrable aspects of $\hat{c}=1$ strings. We consider the circle line theories 0A and 0B at particular radii, and the super affine theories at their self-dual radii.

On two-dimensional tensor network group symmetries

New Journal of Physics
We introduce two-dimensional tensor-network representations of finite groups carrying a 4-cocycle index. We characterize the associated gapped (2+1)D phases that emerge when these anomalous symmetries act on tensor-network ground states.
