    Konishi anomaly and N=1 effective superpotentials from matrix models

    Get PDF
    We discuss the restrictions imposed by the Konishi anomaly on the matrix model approach to the calculation of the effective superpotentials in N=1 SUSY gauge theories with different matter content. It is shown that they correspond to the anomaly deformed Virasoro L0L_0 constraints .Comment: Latex, 8 pages, misprint and the normalization of the condensate in the elliptic model are correcte

    Subword complexes and nil-Hecke moves

    Full text link
    For a finite Coxeter group W, a subword complex is a simplicial complex associated with a pair (Q, \rho), where Q is a word in the alphabet of simple reflections, \rho is a group element. We describe the transformations of such a complex induced by nil-moves and inverse operations on Q in the nil-Hecke monoid corresponding to W. If the complex is polytopal, we also describe such transformations for the dual polytope. For W simply-laced, these descriptions and results of \cite{Go} provide an algorithm for the construction of the subword complex corresponding to (Q, \rho) from the one corresponding to (\delta(Q), \rho), for any sequence of elementary moves reducing the word Q to its Demazure product \delta(Q). The former complex is spherical if and only if the latter one is the (-1)-sphere.Comment: 6 pages.

    Creating the Poor Law Legacy: Institutional Care for Older People Before the Welfare State

    No full text
    Why, despite the universalist aspiration of the British welfare state, was institutional care for poor older people so frequently condemned as inferior? This article seeks an answer in the period before 1945, when local government reform might potentially have raised quality. It adopts a regional case study approach, arguing that this permits access to relevant quantitative and qualitative evidence obscured in national sources, and that concentration on urban experience has hitherto produced a distorted picture. It finds that in contrast to the expansive municipal medical services targeted at the broader population, in this area the assumptions, administrative structures and material inheritance of the Poor Law impeded change and constrained resources. © 2012 Copyright Taylor and Francis Group, LLC
