Intended to provide scientists and engineers at synchrotron radiation facilities with a sound and convenient basis for designing beamlines for monochromatic soft x-ray radiation, this text will also be helpful to the users of synchrotron radiation who want to help ensure that beamlines being built are optimized for the experiments to be performed on them. The primary purpose of a beamline is to capture as much of the light of the source as possible and then to transfer the desired portion of that light as completely as possible to the experiment. With the development of dedicated, brilliant synchrotron radiation sources, the first half of the task has been greatly simplified. The beamline designer must contend with the second half of the problem -- conserving the brilliance of the source through an optical system which monochromatizes and focuses the radiation.
If H is a Hilbert space and T : H ? H is a continous linear operator, a natural question to ask is: What are the closed subspaces M of H for which T M ? M? Of course the famous invariant subspace problem asks whether or not T has any non-trivial invariant subspaces. This monograph is part of a long line of study of the invariant subspaces of the operator T = M (multiplication by the independent variable z, i. e. , M f = zf )on a z z Hilbert space of analytic functions on a bounded domain G in C. The characterization of these M -invariant subspaces is particularly interesting since it entails both the properties z of the functions inside the domain G, their zero sets for example, as well as the behavior of the functions near the boundary of G. The operator M is not only interesting in its z own right but often serves as a model operator for certain classes of linear operators. By this we mean that given an operator T on H with certain properties (certain subnormal operators or two-isometric operators with the right spectral properties, etc. ), there is a Hilbert space of analytic functions on a domain G for which T is unitarity equivalent to M .
Selections from the work of radical feminist author Andrea Dworkin, famous for her antipornography stance and role in the feminist sex wars of the 1980s. Radical feminist author Andrea Dworkin was a caricature of misandrist extremism in the popular imagination and a polarizing figure within the women's movement, infamous for her antipornography stance and her role in the feminist sex wars of the 1980s. She still looms large in feminist demands for sexual freedom, evoked as a censorial demagogue, more than a decade after her death. Among the very first writers to use her own experiences of rape and battery in a revolutionary analysis of male supremacy, Dworkin was a philosopher outside and against the academy who wrote with a singular, apocalyptic urgency. Last Days at Hot Slit brings together selections from Dworkin's work, both fiction and nonfiction, with the aim of putting the contentious positions she's best known for in dialogue with her literary oeuvre. The collection charts her path from the militant primer Woman Hating (1974), to the formally complex polemics of Pornography (1979) and Intercourse (1987) and the raw experimentalism of her final novel Mercy (1990). It also includes “Goodbye to All This” (1983), a scathing chapter from an unpublished manuscript that calls out her feminist adversaries, and “My Suicide” (1999), a despairing long-form essay found on her hard drive after her death in 2005.
