Local cohomology of logarithmic forms [PDF]
, 2012 Let Y be a divisor on a smooth algebraic variety X. We investigate the geometry of the Jacobian scheme of Y, homological invariants derived from logarithmic differential forms along Y, and their relationship with the property that Y is a free divisor ...

Analytical Approach for Orbital Evasion with Space Geometry Considered
International Journal of Aerospace Engineering, 2017 This paper researches an optimal problem of orbital evasion with considering space geometry by using an analytical approach. Firstly, an angles-only relative navigation model is built and the definition of completely nonobservable maneuver is proposed ...

The Atiyah class on algebraic stacks
Forum of Mathematics, SigmaWe generalize Illusie’s definition of the Atiyah class to complexes with quasi-coherent cohomology on arbitrary algebraic stacks. We show that this gives a global obstruction theory for moduli stacks of complexes in algebraic geometry without derived ...

A Note on Derived Geometric Interpretation of Classical Field Theories
, 2019 In this note, we would like to provide a conceptional introduction to the interaction between derived geometry and physics based on the formalism that has been heavily studied by Kevin Costello. Main motivations of our current attempt are as follows: (i)

Hierarchical zonotopal spaces [PDF]
, 2010 Zonotopal algebra interweaves algebraic, geometric and combinatorial properties of a given linear map X. Of basic significance in this theory is the fact that the algebraic structures are derived from the geometry (via a non-linear procedure known as ...

BEBAN KOGNITIF SISWA DALAM PEMBELAJARAN MATERI GEOMETRI
Jurnal Pendidikan: Teori, Penelitian, dan Pengembangan, 2016 The purpose of the study describes the rises of cognitive load of students in learning geometry. The study used a qualitative approach. The results showed that the intrinsic cognitive load is derived from the number of elements of interactivity of ...

Integral transforms and Drinfeld centers in derived algebraic geometry [PDF]
Journal of the American Mathematical Society, 2010 We study the interaction between geometric operations on stacks and algebraic operations on their categories of sheaves. We work in the general setting of derived algebraic geometry: our basic objects are derived stacks X X and their ∞ \infty -categories Q C ( X

Analysis of Cone-Beam Artifacts in off-Centered Circular CT for Four Reconstruction Methods
International Journal of Biomedical Imaging, 2006 Cone-beam (CB) acquisition is increasingly used for truly three-dimensional X-ray computerized tomography (CT). However, tomographic reconstruction from data collected along a circular trajectory with the popular Feldkamp algorithm is known to produce ...
