چکیده
A bstract In the modular linear differential equation (MLDE) approach to classifying rational conformal field theories (RCFTs) both MLDE and RCFT are identified by a pair of non-negative integers [n,l] . n is number characters as well order that solve l , Wronskian index, associated structure zeroes characters. this paper, we study [3,0] [3,2] MLDEs in classify corresponding CFTs. We reduce problem “finite” problem: CFTs with central charge 0 < c ? 96, need perform 6 720 computations for former 20 160 latter. Each computation involves (i) first finding simultaneous solution Diophantine equations (ii) computing Fourier coefficients high checking positivity. case, obtain many character-like solutions: two infinite classes discrete set 303. After accounting various categories known solutions, including Virasoro minimal models, WZW CFTs, Franc-Mason vertex operator algebras Gaberdiel-Hampapura-Mukhi novel coset seem have seven hitherto unknown solutions which could potentially give new also 96: each CFT case obtained adjoining constant character [2,0] CFT, whose classification was achieved Mathur-Mukhi-Sen three decades ago.

2 Two - dimensional Artin groups with CAT ( 0 ) dimension three ∗
We exhibit 3-generator Artin groups which have finite 2-dimensional Eilenberg-Mac Lane spaces, but which do not act properly discontinuously by semi-simple isometries on a 2-dimensional CAT(0) complex. We prove that infinitely many of these groups are the fundamental groups of compact, non-positively curved 3-complexes. These examples show that the geometric dimension of a CAT(0) group may be s...
متن کاملCollecting or Classifying?
Informatics and AI claim that the word is made of objects organized into classes (taxonomies, ontologies,...). In this paper, we explore an other idea: we structure our material relationships by collecting objects within collections, which are never as static as classes.

These maps correspond respectively to the families index theorem of Atiyah and Singer for fibrewise pseudodifferential operators for a smooth fibration of a compact manifold M −→ Y, to the equivariant index for invariant and transversally elliptic operators for the smooth action of a compact Lie group on a compact manifold Z and to the pseudodifferential extension of the numerical index map of ...

An optimization problem for systems that are subject to perturbations where both state observations and control actions are impulsive is here addressed. The dynamics equation is given by a differential inclusion ( ) ( , ( )) x t F t x t ∈ and the optimal strategy is the minimizer of the worst viable perturbation process (minimax). Such formulation is appropriate when noise is barely known but l...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
