We show that Nekrasov instanton partition function for SU(N) gauge theories
satisfies recursion relations in the form of U(1)+Virasoro constraints when
{\beta} = 1. The constraints give a direct support for AGT conjecture for
general quiver gauge ...

We study the inner product of Bethe states in the inhomogeneous periodic XXX
spin-1/2 chain of length L, which is given by the Slavnov determinant formula.
We show that the inner product of an on-shell M-magnon state with a generic
M-magnon state ...

Motivated by application to multiple M5 branes, we study some properties of
non-Abelian two-form gauge theories. We note that the fake curvature condition
which is commonly used in the literature would restrict the dynamics to be
either a free the...

An intriguing coincidence between the partition function of super Yang-Mills
theory and correlation functions of 2d Toda system has been heavily studied
recently. While the partition function of gauge theory was explored by
Nekrasov, the correlati...

We give some evidences which imply that W(1+infinity) algebra describes the
symmetry behind AGT(-W) conjecture: a correspondence between the partition
function of N=2 supersymmetric quiver gauge theories and the correlators of
Liouville (Toda) fie...

We construct a non-Abelian gauge theory of chiral 2-forms (self-dual gauge
fields) in 6 dimensions with a spatial direction compactified on a circle of
radius R. It has the following two properties. (1) It reduces to the Yang-Mills
theory in 5 dim...

We give some evidences of the AGT-W relation between SU(3) quiver gauge

5-point correlation functions in the lower orders and confirm the agreement

We discuss the correspondence between degenerate fields of the W_N algebra
and punctures of Gaiotto's description of the Seiberg-Witten curve of N=2
superconformal gauge theories. Namely, we find that the type of degenerate
fields of the W_N algeb...

In our previous paper, it was shown that BLG model based on a Lorentzian
metric 3-algebra gives Dp-brane action whose worldvolume is compactified on
torus T^d (d=p-2). Here the 3-algebra was a generalized one with d+1 pairs of
Lorentzian metric ge...

We show that there exists a cut-off version of Nambu-Poisson bracket which
defines a finite dimensional Lie 3-algebra. The algebra still satisfies the
fundamental identity and thus produces N=8 supersymmetric BLG type equation of
motion for multip...

We investigate the Bagger-Lambert-Gustavsson model associated with the
Nambu-Poisson algebra as a theory describing a single M5-brane. We argue that
the model is a gauge theory associated with the volume-preserving
diffeomorphism in the three-dime...

We present two derivations of the multiple D2 action from the multiple

start from Lie 3-algebra associated with given (arbitrary) Lie algebra. The Lie
3-algebra metric i...

the Nambu-Poisson structure of three dimensional manifolds. We show that the

can be identified with its idempotents. The algebra can be identified with a
