    Holograph letter from [M.] Browne, St. Francis Xavier's Upper Gardiner Street, Dublin, to Fr. MacMahon [Rome]. Acting on behalf of the Ursuline community in Waterford, asking him to call on Hagan at the Irish College to enquire about the Bishop of Waterford's request for an apostolic permission to sell property. The latter is held by the nuns in Dublin, and they oppose the sale instigated by the other two owning parties

    Community Detection for Correlation Matrices

    No full text
    A challenging problem in the study of complex systems is that of resolving, without prior information, the emergent, mesoscopic organization determined by groups of units whose dynamical activity is more strongly correlated internally than with the rest of the system. The existing techniques to filter correlations are not explicitly oriented towards identifying such modules and can suffer from an unavoidable information loss. A promising alternative is that of employing community detection techniques developed in network theory. Unfortunately, this approach has focused predominantly on replacing network data with correlation matrices, a procedure that we show to be intrinsically biased because of its inconsistency with the null hypotheses underlying the existing algorithms. Here, we introduce, via a consistent redefinition of null models based on random matrix theory, the appropriate correlation-based counterparts of the most popular community detection techniques. Our methods can filter out both unit-specific noise and system-wide dependencies, and the resulting communities are internally correlated and mutually anticorrelated. We also implement multiresolution and multifrequency approaches revealing hierarchically nested subcommunities with “hard” cores and “soft” peripheries. We apply our techniques to several financial time series and identify mesoscopic groups of stocks which are irreducible to a standard, sectorial taxonomy; detect “soft stocks” that alternate between communities; and discuss implications for portfolio optimization and risk management

    The MacMahon Master Theorem for right quantum g^l(mn)\hat gl(m|n)

    No full text
    International audienceWe prove an analogue of the MacMahon Master Theorem for the right quantumsuperalgebras. In particular, we obtain a new and simple proof of this theoremfor the right quantum algebras. In the super case the theorem is then used toconstruct higher order Sugawara operators for the affine Lie superalgebragl^(mn)\widehat{\mathfrak{gl}}(m|n) in an explicit form. The operators are elementsof a completed universal enveloping algebra of gl^(mn)\widehat{\mathfrak{gl}}(m|n)at the critical level. They occur as the coefficients in the expansion of anoncommutative Berezinian and as the traces of powers of generator matrices.The same construction yields higher Hamiltonians for the Gaudin modelassociated with the Lie superalgebra gl(mn)\mathfrak{gl}(m|n). We also use theSugawara operators to produce algebraically independent generators of thealgebra of singular vectors of any generic Verma module at the critical levelover the affine Lie superalgebra
