Index for a mutation loop

Tsukasa Ishibashi, Yuji Terashima

Motivated by the 3d-3d correspondence, we introduce an index for a mutation loop of a quiver and an integer . We prove its integrality $\mathcal{I}_…

Homological blocks with simple Lie algebras and Witten--Reshetikhin--Turaev invariants

Yuya Murakami, Yuji Terashima

In this article, for any Seifert fibered homology 3-sphere, we introduce homological blocks with simple Lie algebra and prove that its radial limits are identified with the Witten-…

Discrete Higher Berry Phases and Matrix Product States

Shuhei Ohyama, Yuji Terashima, Ken Shiozaki

A -parameter family of invertible states gives a topological transport phenomenon, similar to the Thouless pumping. As a natural generalization of this, we can consider a family…

Quantum invariants of closed framed -manifolds based on ideal triangulations

Serban Matei Mihalache, Sakie Suzuki, Yuji Terashima

We construct a new type of quantum invariant of closed framed -manifolds with the vanishing first Betti number. The invariant is defined for any finite dimensional Hopf algebra,…

On adjoint homological Selmer modules for SL-representations of knot groups

Takahiro Kitayama, Masanori Morishita, Ryoto Tange +1

We introduce the adjoint homological Selmer module for an SL-representation of a knot group, which may be seen as a knot theoretic analogue of the dual adjoint Selmer module fo…

Modular transformations of homological blocks for Seifert fibered homology -spheres

Toshiki Matsusaka, Yuji Terashima

In this article, for any Seifert fibered integral homology 3-sphere, we give explicit modular transformation formulas of homological blocks introduced by Gukov-Pei-Putrov-Vafa. Mor…

The colored Jones polynomials as vortex partition functions

Masahide Manabe, Seiji Terashima, Yuji Terashima

We construct 3D abelian gauge theories on labeled by knot diagrams whose K-theoretic vortex partition functions, each of which is…

The Heisenberg double of involutory Hopf algebras and invariants of closed -manifolds

Serban Matei Mihalache, Sakie Suzuki, Yuji Terashima

We construct an invariant of closed oriented -manifolds using a finite dimensional, involutory, unimodular and counimodular Hopf algebra . We use the framework of normal o-gr…

Arithmetic Orr invariants of absolute Galois groups

Hisatoshi Kodani, Yuji Terashima

Based on the analogies between mapping class groups and absolute Galois groups, we introduce an arithmetic pro- analogue of Orr invariants for a Galois element associated wit…

Witten-Reshetikhin-Turaev function for a knot in Seifert manifolds

Hiroyuki Fuji, Kohei Iwaki, Hitoshi Murakami +1

In this paper, for a Seifert loop (i.e., a knot in a Seifert three-manifold), first we give a family of an explicit function whose special values at roots of unity are id…

On -dimensional foliated dynamical systems and Hilbert type reciprocity law

Junhyeong Kim, Masanori Morishita, Takeo Noda +1

We show some fundamental results concerning -dimensional foliated dynamical systems (FDS for short) introduced by Deninger. Firstly, we give a decomposition theorem for an F…

Cluster variables, ancestral triangles and Alexander polynomials

Wataru Nagai, Yuji Terashima

In this paper, we show that Alexander polynomials for any 2-bridge knots are specializations of cluster variables. A key tool is an ancestral triangle which appeared in both quantu…

Quiver mutation sequences and -binomial identities

Akishi Kato, Yuma Mizuno, Yuji Terashima

In this paper, first we introduce a quantity called a partition function for a quiver mutation sequence. The partition function is a generating function whose weight is a -binom…

Arithmetic topology in Ihara theory

Hisatoshi Kodani, Masanori Morishita, Yuji Terashima

Ihara initiated to study a certain Galois representation which may be seen as an arithmetic analogue of the Artin representation of a pure braid group. We pursue the analogies in I…

Homotopy theory of -algebras and characteristic classes of fiber bundles

Hiroshige Kajiura, Takahiro Matsuyuki, Yuji Terashima

In this paper we give a Chern-Weil-type construction of characteristic classes of fiber bundles, based on homotopy theory of C-infinity algebras. Our idea is to replace a family of…

Characteristic classes of fiber bundles

Takahiro Matsuyuki, Yuji Terashima

In this paper, we construct new characteristic classes of fiber bundles via flat connections with values in infinite-dimensional Lie algberas of derivations. In fact, choosing a fi…

On certain L-functions for deformations of knot group representations

Takahiro Kitayama, Masanori Morishita, Ryoto Tange +1

We study the twisted knot module for the universal deformation of an -representation of a knot group, and introduce an associated -function, which may be seen as an…

Quantum dilogarithms and partition q-series

Akishi Kato, Yuji Terashima

In our previous work [arXiv:1403.6569], we introduced the partition q-series for mutation loop --- a loop in exchange quiver. In this paper, we show that for certain class of mutat…

Quiver mutation loops and partition q-series

Akishi Kato, Yuji Terashima

A quiver mutation loop is a sequence of mutations and vertex relabelings, along which a quiver transforms back to the original form. For a given mutation loop, we introduce a quant…
