The Canonical Sheaf of Du Bois Singularities
We prove that a Cohen-Macaulay normal variety X has Du Bois singularities if and only if π∗ωX′(G) ≃ ωX for a log resolution π : X ′ → X , where G is the reduced exceptional divisor of π. Many basic theorems about Du Bois singularities become transparent using this characterization (including the fact that Cohen-Macaulay log canonical singularities are Du Bois). We also give a straightforward an...
متن کاملA Simple Characterization of Du Bois Singularities
We prove the following theorem characterizing Du Bois singularities. Suppose that Y is smooth and that X is a reduced closed subscheme. Let π : e Y → Y be a log resolution of X in Y that is an isomorphism outside of X. If E is the reduced pre-image of X in e Y , then X has Du Bois singularities if and only if the natural map ØX → Rπ∗ØE is a quasi-isomorphism. We also deduce Kollár’s conjecture ...
متن کاملF-injective Singularities Are Du Bois
In this paper, we prove that singularities of F -injective type are Du Bois. This extends the correspondence between singularities associated to the minimal model program and singularities defined by the action of Frobenius in positive characteristic.
متن کاملThe Axial Age and the Problems of the Twentieth Century: Du Bois, Jaspers, and Universal History
The axial age debate has put big questions of social and cultural change back on the agenda of sociology. This paper takes this development as an occasion to reflect on how social thought works with (and against) nineteenth-century intellectual traditions in its efforts to understand history on a macro scale. Karl Jaspers, who initially formulated the axial age thesis in The Origin and Goal of ...
متن کاملW. E. B. Du Bois: Interpreting Religion and the Problem of the Negro Church
W. E. B. Du Bois’s contribution to the study of the Negro Church was his historical argument about the viability and influence of African culture. Du Bois asserted the partial autonomy and creativity of black culture. This was a crucial achievement in his day when normative theories of African cultural “backwardness” prevailed. Du Bois’s detailed analyses of particular local black communities a...
