p-adic deformation of algebraic cycle classes [PDF]
, 2013 We study the p-adic deformation properties of algebraic cycle classes modulo rational equivalence. We show that the crystalline Chern character of a vector bundle lies in a certain part of the Hodge filtration if and only if, rationally, the class of the

Virtual moduli cycles and Gromov-Witten invariants of algebraic varieties [PDF]
, 1998 We introduce a method of constructing the virtual cycle of any scheme associated with a tangent-obstruction complex. We apply this method to constructing the virtual moduli cycle of the moduli of stable maps from n-pointed genus g curves to any smooth ...

Towards an algebraic method of solar cycle prediction [PDF]
Journal of Space Weather and Space Climate, 2020 An algebraic method for the reconstruction and potentially prediction of the solar dipole moment value at sunspot minimum (known to be a good predictor of the amplitude of the next solar cycle) was suggested in the first paper in this series.

Torsion algebraic cycles and complex cobordism [PDF]
, 1996 We show that the cycle map on a variety X, from algebraic cycles modulo algebraic equivalence to integer cohomology, lifts canonically to a topologically defined quotient of the complex cobordism ring of X. This more refined cycle map gives a topological

NORMAL FUNCTIONS FOR ALGEBRAICALLY TRIVIAL CYCLES ARE ALGEBRAIC FOR ARITHMETIC REASONS
Forum of Mathematics, Sigma, 2019 For families of smooth complex projective varieties, we show that normal functions arising from algebraically trivial cycle classes are algebraic and defined over the field of definition of the family.

OBSTRUCTIONS TO ALGEBRAIZING TOPOLOGICAL VECTOR BUNDLES
Forum of Mathematics, Sigma, 2019 Suppose $X$ is a smooth complex algebraic variety. A necessary condition for a complex topological vector bundle on $X$ (viewed as a complex manifold) to be algebraic is that all Chern classes must be algebraic cohomology classes, that is, lie in the ...

A nontrivial algebraic cycle in the Jacobian variety of the Klein quartic
, 2005 We prove some value of the harmonic volume for the Klein quartic C is nonzero modulo $$\frac{1}{2}{\mathbb{Z}}$$ , using special values of the generalized hypergeometric function 3F2.

The effectiveness of contextual approach on students' comprehension ability
Journal 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

Permutation actions on Quiver Grassmannians for the equioriented cycle via GKM-theory [PDF]
Journal of Algebraic Combinatorics, 2021 In our previous work, we equipped quiver Grassmannians for nilpotent representations of the equioriented cycle with an action of an algebraic torus. We show here that the equivariant cohomology ring is acted upon by a product of symmetric groups and we ...
