The factorized Smatrix of CFT/AdS
, 2004
"... We argue that the recently discovered integrability in the largeN 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 ..."

dilatation operator nor the string sigma model’s quantum Hamiltonian, but instead the respective factorized Smatrix. To illustrate the idea, we focus on the closed fermionic su(11) sector of the N = 4 gauge theory. We introduce a new technique, the perturbative asymptotic Bethe ansatz, and use
An Existence Proof for Interacting Quantum Field Theories with a Factorizing SMatrix
 Commun. Mat. Phys
"... Within the context of quantum field theories on twodimensional Minkowski space with a factorizing Smatrix, a new construction scheme for relativistic model theories is carried out. We show that for a large class of such Smatrices, there exists an associated local quantum field theory in the sense ..."

On the existence of local observables in theories with a factorizing Smatrix
 J. Phys. A
, 2005
"... A recently proposed criterion for the existence of local quantum fields with a prescribed factorizing scattering matrix is verified in a nontrivial model, thereby establishing a new constructive approach to quantum field theory in a particular example. The existence proof is accomplished by analyzi ..."

Hermitian analyticity versus real analyticity in twodimensional factorized Smatrix theories
"... The constraints implied by analyticity in twodimensional factorised Smatrix theories are reviewed. Whenever the theory is not timereversal invariant, it is argued that the familiar condition of ‘Real analyticity ’ for the Smatrix amplitudes has to be superseded by a different one known as ‘Hermi ..."

, 2009
"... As the Netflix Prize competition has demonstrated, matrix factorization models are superior to classic nearestneighbor techniques for producing product recommendations, allowing the incorporation of additional information such as implicit feedback, temporal effects, and confidence levels. Modern co ..."

The AdS5 × S 5 superstring worldsheet Smatrix and crossing symmetry
, 2008
"... An Smatrix satisying the YangBaxter equation with symmetries relevant to the AdS5 × S 5 superstring has recently been determined up to an unknown scalar factor. Such scalar factors are typically fixed using crossing relations, however due to the lack of conventional relativistic invariance, in thi ..."

The Dantzig selector: statistical estimation when p is much larger than n
, 2005
"... In many important statistical applications, the number of variables or parameters p is much larger than the number of observations n. Suppose then that we have observations y = Ax + z, where x ∈ R p is a parameter vector of interest, A is a data matrix with possibly far fewer rows than columns, n ≪ ..."

The Determinants of Credit Spread Changes.
 Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

Similarly, Duffie and Singleton (1999) find that both creditrisk and liquidity factors are necessary to explain innovations in U.S. swap rates. However, when analyzing the residuals they are unable to find explanatory factors
