Scale-invariant Feature Extraction of Neural Network and Renormalization Group Flow
Satoshi Iso, Shotaro Shiba, Sumito Yokoo
Theoretical understanding of how deep neural network (DNN) extracts features from input images is still unclear, but it is widely believed that the extraction is performed hierarch…
M2- and M5-branes in E11 Current Algebra Formulation of M-theory
Shotaro Shiba, Hirotaka Sugawara
Equations of motion for M2- and M5-branes are written down in the current algebra formulation of M-theory. These branes correspond to currents of the second and the fifth…
Microstates of black holes in expanding universe from interacting branes
Shotaro Shiba
Thermodynamics of the near extremal black p-branes can be described by collective motions of gravitationally interacting branes. This proposal is called the p-soup model. In this p…
Thermodynamics of Intersecting Black Branes from Interacting Elementary Branes
Takeshi Morita, Shotaro Shiba
If an Einstein-Maxwell-Dilaton system admits the extreme brane solution in which no force works between the parallel branes, the collective motion of nearly parallel branes exhibit…
Moduli dynamics as a predictive tool for thermal maximally supersymmetric Yang-Mills at large N
Takeshi Morita, Shotaro Shiba, Toby Wiseman +1
Maximally supersymmetric (p+1)-dimensional Yang-Mills theory at large N and finite temperature, with possibly compact spatial directions, has a rich phase structure. Strongly coupl…
Microstates of D1-D5(-P) black holes as interacting D-branes
Takeshi Morita, Shotaro Shiba
In our previous study [1] (1311.6540), we figured out that the thermodynamics of the near extremal black -branes can be explained as the collective motions of gravitationally in…
Warm p-soup and near extremal black holes
Takeshi Morita, Shotaro Shiba, Toby Wiseman +1
We consider a model of D-dimensional supergravity coupled to elementary p-branes. We use gravitational arguments to deduce the low energy effective theory of N nearly parallel bran…
A new look at instantons and large-N limit
Tatsuo Azeyanagi, Masanori Hanada, Masazumi Honda +2
We analyze instantons in the very strongly coupled large- limit ( with fixed) of large- gauge theories, where the effect of the instantons remains finite. B…
Thermodynamics of black M-branes from SCFTs
Takeshi Morita, Shotaro Shiba
We discuss thermodynamics of N M2-branes at strong coupling from the ABJM theory by employing the Smilga-Wiseman method, which explains the black Dp-brane thermodynamics from the m…
W_3 irregular states and isolated N=2 superconformal field theories
Hiroaki Kanno, Kazunobu Maruyoshi, Shotaro Shiba +1
We explore the proposal that the six-dimensional (2,0) theory on the Riemann surface with irregular punctures leads to a four-dimensional gauge theory coupled to the isolated N=2 s…
Numerical studies of the ABJM theory for arbitrary N at arbitrary coupling constant
Masanori Hanada, Masazumi Honda, Yoshinori Honma +3
We show that the ABJM theory, which is an N=6 superconformal U(N)*U(N) Chern-Simons gauge theory, can be studied for arbitrary N at arbitrary coupling constant by applying a simple…
Notes on 3-point functions of A_{N-1} Toda theory and AGT-W relation for SU(N) quiver
Shotaro Shiba
We study on the property of 3-point correlation functions of 2-dim A_{N-1} Toda field theory, and show the correspondence with the 1-loop part of partition function of 4-dim N=2 SU…
W(1+infinity) algebra as a symmetry behind AGT relation
Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba
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 supersymmetri…
Dp-branes, NS5-branes and U-duality from nonabelian (2,0) theory with Lie 3-algebra
Yoshinori Honma, Morirou Ogawa, Shotaro Shiba
We derive the super Yang-Mills action of Dp-branes on a torus T^{p-4} from the nonabelian (2,0) theory with Lie 3-algebra. Our realization is based on Lie 3-algebra with pairs of L…
Analysis of correlation functions in Toda theory and AGT-W relation for SU(3) quiver
Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba
We give some evidences of the AGT-W relation between SU(3) quiver gauge theories and A_2 Toda theory. In particular, we derive the explicit form of 5-point correlation functions in…
N=2 gauge theories and degenerate fields of Toda theory
Shoichi Kanno, Yutaka Matsuo, Shotaro Shiba +1
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.…
Aspects of U-duality in BLG models with Lorentzian metric 3-algebras
Takayuki Kobo, Yutaka Matsuo, Shotaro Shiba
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-a…
Lorentzian Lie (3-)algebra and toroidal compactification of M/string theory
Pei-Ming Ho, Yutaka Matsuo, Shotaro Shiba
We construct a class of Lie 3-algebras with an arbitrary number of pairs of generators with Lorentzian signature metric. Some examples are given and corresponding BLG models are st…
Truncated Nambu-Poisson Bracket and Entropy Formula for Multiple Membranes
Chong-Sun Chu, Pei-Ming Ho, Yutaka Matsuo +1
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…

Pei-Ming Ho, Yosuke Imamura, Yutaka Matsuo +1
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 ass…
