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 ...

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 ...

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 ...

Quadratic forms and Clifford algebras on derived stacks [PDF]
, 2016 In this paper we present an approach to quadratic structures in derived algebraic geometry. We define derived n-shifted quadratic complexes, over derived affine stacks and over general derived stacks, and give several examples of those.

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 ...

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals
Advanced Functional Materials, EarlyView.Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.
