A theory for multiresolution signal decomposition : the wavelet representation
- IEEE Transaction on Pattern Analysis and Machine Intelligence
, 1989
"... Abstract-Multiresolution representations are very effective for analyzing the information content of images. We study the properties of the operator which approximates a signal at a given resolution. We show that the difference of information between the approximation of a signal at the resolutions ..."

Long-range psu(2, 2|4) Bethe Ansätze for Gauge Theory and Strings
, 2005
"... We generalize various existing higher-loop Bethe ansätze for simple sectors of the integrable long-range dynamic spin chain describing planar N = 4 Super Yang-Mills Theory to the full psu(2, 2|4) symmetry and, asymptotically, to arbitrary loop order. We perform a large number of tests of our conject ..."

Bethe ansatz from the gauge theory dilatation operator. We conjecture novel all-order S-matrices for the su(1|2) and psu(1, 1|2) subsectors, and show that they satisfy the Yang-Baxter equation. Throughout the paper, we muse about the idea that quantum string theory on AdS5 × S 5 is also described by a
Exactly marginal operators and duality in four-dimensional N=1 supersymmetric Gauge theory
- PHYS. B
, 1995
"... We show that manifolds of fixed points, which are generated by exactly marginal operators, are common in N=1 supersymmetric gauge theory. We present a unified and simple prescription for identifying these operators, using tools similar to those employed in two-dimensional N=2 supersymmetry. In parti ..."

Electric-Magnetic duality and the geometric Langlands program
, 2006
"... The geometric Langlands program can be described in a natural way by compactifying on a Riemann surface C a twisted version of N = 4 super Yang-Mills theory in four dimensions. The key ingredients are electric-magnetic duality of gauge theory, mirror symmetry of sigma-models, branes, Wilson and ’t H ..."

Renormalization group flows from holography -- Supersymmetry and a c-theorem
- ADV THEOR. MATH. PHYS
, 1999
"... We obtain first order equations that determine a supersymmetric kink solution in fivedimensional N = 8 gauged supergravity. The kink interpolates between an exterior anti-de Sitter region with maximal supersymmetry and an interior anti-de Sitter region with one quarter of the maximal supersymmetry. ..."

between fields of bulk supergravity in the interior anti-de Sitter region and composite operators of the infrared field theory. We also point out that the truncation used to find the reduced symmetry critical point can be extended to obtain a new N = 4 gauged supergravity theory holographically dual to a
Covariant operator formalism of gauge theories and quantum gravity,” World Sci. Lect. Notes Phys
, 1990
"... The new method proposed previously for solving the covariant operator formalism of quantum Einstein gravity is applied to quantum electrodynamics as an exercise of the application to quantum chromodynamics. The purposes of doing this are to establish the details of the method and to reconfirm the va ..."

the validity of the method. The Wightman functions are explicitly constructed, at tree and one-loop levels, so as to be consistent with four-dimensional multiple (anti)commutators and with the energy-positivity condition. Quantum chromodynamics is a non-abelian gauge theory, for which the covariant operator
The factorized S-matrix of CFT/AdS
, 2004
"... We argue that the recently discovered integrability in the large-N CFT/AdS system is equivalent to diffractionless scattering of the corresponding hidden elementary excitations. This suggests that, perhaps, the key tool for finding the spectrum of this system is neither the gauge theory’s dilatati ..."

Chiral rings and anomalies in supersymmetric gauge theory

, 2002
"... Motivated by recent work of Dijkgraaf and Vafa, we study anomalies and the chiral ring structure in a supersymmetric U(N) gauge theory with an adjoint chiral superfield and an arbitrary superpotential. A certain generalization of the Konishi anomaly leads to an equation which is identical to the loo ..."

Gauge-string duality for (non)supersymmetric deformations of N=4 Super Yang-Mills theory
, 2005
"... We consider a non-supersymmetric example of the AdS/CFT duality which generalizes the supersymmetric exactly marginal deformation constructed in hep-th/0502086. The string theory background we use was found in hep-th/0503201 from the AdS5 × S 5 by a combination of T-dualities and shifts of angular c ..."

is to make a special choice of the spin chain Hamiltonian representing the 1-loop gauge theory dilatation operator. This choice is adapted to low-energy approximation, i.e. it allows one to capture the right vacuum states and the “macroscopic spin wave ” sector of states of the spin chain in the continuum
