Pseudo-dualizing complexes and pseudo-derived categories
, 2020 The definition of a pseudo-dualizing complex is obtained from that of a dualizing complex by dropping the injective dimension condition, while retaining the finite generatedness and homothety isomorphism conditions.

Derived categories and rationality of conic bundles [PDF]
, 2012 We show that a standard conic bundle over a minimal rational surface is rational and its Jacobian splits as the direct sum of Jacobians of curves if and only if its derived category admits a semiorthogonal decomposition by exceptional objects and the ...

Geometricity for derived categories of algebraic stacks [PDF]
, 2016 We prove that the dg category of perfect complexes on a smooth, proper Deligne–Mumford stack over a field of characteristic zero is geometric in the sense of Orlov, and in particular smooth and proper.

Thick subcategories of discrete derived categories [PDF]
Advances in Mathematics, 2016 We classify the thick subcategories of discrete derived categories. To do this we introduce certain generating sets called arc-collections which correspond to configurations of non-crossing arcs on a geometric model.

Derived categories and the analytic approach to general reciprocity laws. Part I
International Journal of Mathematics and Mathematical Sciences, 2005 We reformulate Hecke's open problem of 1923, regarding the Fourier-analytic proof of higher reciprocity laws, as a theorem about morphisms involving stratified topological spaces.

Glossa, 2018 Traditionally, languages are assumed to minimally manifest a distinction between nouns and verbs. This assumption has occasionally been debated in the theoretical linguistic literature, in particular in the context of challenging verbal noun ...

Reconstructions of droughts in Germany since 1500 – combining hermeneutic information and instrumental records in historical and modern perspectives [PDF]
Climate of the Past, 2020 The present article deals with the reconstruction of drought time series in Germany since 1500. The reconstructions are based on historical records from the virtual research environment Tambora (tambora.org, 2018) and official instrumental records.

Derived categories of curves as components of Fano manifolds [PDF]
Journal of the London Mathematical Society, 2016 We prove that the derived category D(C) of a generic curve of genus greater than one embeds into the derived category D(M) of the moduli space M of rank 2 stable bundles on C with fixed determinant of odd degree.

Derived Categories and the Analytic Approach to General Reciprocity Laws: Part III
International Journal of Mathematics and Mathematical Sciences, 2010 Building on the scaffolding constructed in the first two articles in this series, we now proceed to the geometric phase of our sheaf (-complex) theoretic quasidualization of Kubota's formalism for n-Hilbert reciprocity.
