Nodes as Composite Operators in Matrix Models 1
Riemann surfaces with nodes can be described by introducing simple composite operators in matrix models. In the case of the Kontsevich model, it is sufficient to add the quadratic, but “non-propagating”, term (tr[X]) to the Lagrangian. The corresponding JenkinsStrebel differentials have pairwise identified simple poles. The result is in agreement with a conjecture formulated by Kontsevich and r...
متن کاملNonnegative matrix factorisations as probabilistic inference in composite models
We develop an interpretation of nonnegative matrix factorization (NMF) methods based on Euclidean distance, Kullback-Leibler and Itakura-Saito divergences in a probabilistic framework. We describe how these factorizations are implicit in a well-defined statistical model of superimposed components, either Gaussian or Poisson distributed, and are equivalent to maximum likelihood estimation of eit...
متن کاملBoundary operators in the O ( n ) and RSOS matrix models
We study the new boundary condition of the O(n) model proposed by Jacobsen and Saleur using the matrix model. The spectrum of boundary operators and their conformal weights are obtained by solving the loop equations. Using the diagrammatic expansion of the matrix model as well as the loop equations, we make an explicit correspondence between the new boundary condition of the O(n) model and the ...
متن کاملRandom Matrix Models for Dirac Operators at finite Lattice Spacing
We study discretization effects of the Wilson and staggered Dirac operator with Nc > 2 using chiral random matrix theory (chRMT). We obtain analytical results for the joint probability density of Wilson-chRMT in terms of a determinantal expression over complex pairs of eigenvalues, and real eigenvalues corresponding to eigenvectors of positive or negative chirality as well as for the eigenvalue...
متن کاملRenormalisation of composite operators in lattice perturbation theory with clover fermions: non-forward matrix elements
We consider the renormalisation of lattice QCD operators with one and two covariant derivatives related to the first and second moments of generalised parton distributions and meson distribution amplitudes. Employing the clover fermion action we calculate their non-forward quark matrix elements in one-loop lattice perturbation theory. For some representations of the hypercubic group commonly us...
