Algebraic equivalence of real algebraic cycles [PDF]

open access: yesAnnales de l'Institut Fourier, 1999
Given a compact nonsingular real algebraic variety we study the algebraic cohomology classes given by algebraic cycles algebraically equivalent to zero.

Algebraic cycles and local anomalies in F-theory

open access: yesJournal of High Energy Physics, 2017
We introduce a set of identities in the cohomology ring of elliptic fibrations which are equivalent to the cancellation of gauge and mixed gauge-gravitational anomalies in F-theory compactifications to four and six dimensions.

A short history of algebraic statistics [PDF]

open access: yes, 2008
In algebraic statistics, computational techniques from algebraic geometry become tools to address statistical problems. This, in turn, may prompt research in algebraic geometry. The basic ideas at the core of algebraic statistics will be presented. In

Protein–protein interaction network of E. coli K‐12 has significant high‐dimensional cavities: new insights from algebraic topological studies

open access: yesFEBS Open Bio, 2022
As a model system, Escherichia coli has been used to study various life processes. A dramatic paradigm shift has occurred in recent years, with the study of single proteins moving toward the study of dynamically interacting proteins, especially protein ...

The effectiveness of contextual approach on students' comprehension ability

open access: yesJournal of Advanced Sciences and Mathematics Education, 2021
This study aimed to determine the effectiveness of the contextual approach in improving students' algebraic arithmetic operations. This research is a Classroom Action Research (CAR) conducted in two cycles with each cycle consisting of two meetings. Data

Algebraic cycles and intersection homology [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
We consider Dubson’s conjecture that the fundamental class in homology of an algebraic cycle on a complex algebraic variety is the image of a middle intersection homology class. In the case when the variety has only isolated singularities, we prove it for rational coefficients, and we give a counterexample to it for integral ...

Quadratic forms and linear algebraic groups [PDF]

open access: yes, 2009
Topics discussed at the workshop Quadratic Forms and Linear Algebraic Groups included besides the algebraic theory of quadratic and Hermitian forms and their Witt groups several aspects of the theory of linear algebraic groups and homogeneous varieties ...

A Hodge Theory-Driven Quantum Mapping Between Calabi-Yau Manifolds and Nuclear Topology: First-Principles Derivation and Experimental Verification [PDF]

open access: yesPhysics Access
This study adopts Hodge theory as a rigorous mathematical framework to construct a quantitative mapping system between the high-dimensional topological invariants of CalabiYau (CY) manifolds and nuclear physics parameters, thereby establishing a strict ...
