  1. 11. Period integrals and other direct images of D-modules

    Författare :Ketil Tveiten; Rikard Bøgvad; Uli Walther; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; D-modules; Rings of differential operators; Period integrals; Mathematics; matematik;

    Sammanfattning : This thesis consists of three papers, each touching on a different aspect of the theory of rings of differential operators and D-modules. In particular, an aim is to provide and make explicit good examples of D-module directimages, which are all but absent in the existing literature. LÄS MER
