G 4 flux, algebraic cycles and complex structure moduli stabilization
Journal of High Energy Physics, 2021 We construct G 4 fluxes that stabilize all of the 426 complex structure moduli of the sextic Calabi-Yau fourfold at the Fermat point. Studying flux stabilization usually requires solving Picard-Fuchs equations, which becomes unfeasible for models with ...

Non-algebraic limit cycles in Holling type III zooplankton-phytoplankton models
Cubo, 2021 We prove that for certain polynomial differential equations in the plane arising from predator-prey type III models with generalized rational functional response, any algebraic solution should be a rational function. As a consequence, limit cycles, which

Algebraic cycles and local anomalies in F-theory
Journal 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.

Using SAT Solvers to Finding Short Cycles in Cryptographic Algorithms [PDF]
International Journal of Electronics and Telecommunications, 2020 A desirable property of iterated cryptographic algorithms, such as stream ciphers or pseudo-random generators, is the lack of short cycles. Many of the previously mentioned algorithms are based on the use of linear feedback shift registers (LFSR) and ...

Algebraic cycles and approximation theorems in real algebraic geometry [PDF]
Transactions of the American Mathematical Society, 1993 Let \(M\) be a compact orientable smooth manifold of dimension \(\geq 5\). This paper shows which subgroups \(G \subset H_ 2 (M, {\mathbf Z}/2)\) can possibly be the subgroup of two dimensional algebraic cycles in an algebraic model of \(M\). It shows that the possible \(G\)'s are exactly those containing the Poincaré dual of the second Stieffel ...

FEBS 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 ...

Algebraic cycles and intersection homology [PDF]
Proceedings 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 ...

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

Algebraic cycles representing cohomology operations [PDF]
Mathematische Zeitschrift, 2016 In this paper we show that certain universal homology classes which are fundamental in topology are algebraic. To be specific, the products of Eilenberg-MacLane spaces ${\cal K}_{2q} \equiv K({\Bbb Z},2) \times K({\Bbb Z}, 4) \times ... \times K({\Bbb Z}, 2q)$ have models which are limits of complex projective varieties.

Algebraic Cycles and Additive Dilogarithm [PDF]
International Mathematics Research Notices, 2010 15 pages. v2: major revision. Notations made coherent. Relationship among several versions of "additive Bloch groups": 1) Cathelineau-Goncharov 2) Bloch-Esnault, and 3) the cycle-theoretic one in this paper, clarified., v3: typos, grammatical errors corrected.
