Schubert Derivations on the Infinite Wedge Power
(2020-01-01)
The Schubert derivation is a distinguished Hasse–Schmidt derivation on the exterior algebra of a free abelian group, encoding the formalism of Schubert calculus for all Grassmannians at once. The purpose of this paper is ...
SPECIFYING ACTIVE RULES FOR DATABASE MAINTENANCE
(SPRINGER, 2000)
In this article we extend previous work on the development of logical foundations for the specification of the dynamics of databases. In particular, we deal with two problems. Firstly, the derivation of active rules that ...
The Mittag–Leffler function and its application to the ultra-hyperbolic time-fractional diffusion-wave equation
(Taylor & Francis Ltd, 2016-05)
In this paper we study an n-dimensional generalization of time-fractional diffusion-wave equation, where the Laplacian operator is replaced by the ultra-hyperbolic operator and the time-fractional derivative is taken in ...

(Taylor & Francis Group, 2016-03)
In this paper we study an n-dimensional generalization of timefractional diffusion-wave equation, where the Laplacian operator is replaced by the ultra-hyperbolic operator and the time-fractional derivative is taken in the ...

A theoretical and experimental study to unequivocal structural assignment of tetrahydroquinoline derivatives
(2013-06-24)
The tetrahydroquinoline derivatives can be easily synthesized through Povarov reaction and have several important biological activities. This work describes a comparative study for the unequivocal assignment of molecular ...
Communiols E-H: New polyketide metabolites from the coprophilous fungus Podospora communis
(2005-03-01)
Communiols E-H (1-4), four new polyketide-derived natural products containing furanocyclopentane, furanocyclopentene, cyclopentene, or γ-lactone moieties, have been isolated from two geographically distinct isolates of the ...
