Planar chemical reaction systems with algebraic and non-algebraic limit cycles [PDF]
Journal of Mathematical BiologyThe Hilbert number H(n) is defined as the maximum number of limit cycles of a planar autonomous system of ordinary differential equations (ODEs) with right-hand sides containing polynomials of degree at most n ∈ N.

Cycles on Algebraic Varieties [PDF]
Nagoya Mathematical Journal, 1955 In the present note, applying the theory of harmonic integrals, we shall show some results on cycles on algebraic varieties and give a new birational invariant.

Mixed motives and algebraic cycles III [PDF]
Mathematical Research Letters, 1995 For part I see M. Hanamura, Math. Res. Lett. 2, No. 6, 811-821 (1995; Zbl 0867.14003). In this third part of the author's series of articles on mixed motives and algebraic cycles, the author applies his previous constructions to another crucial conjecture in the theory of motives, namely to the conjecture of the existence of the so-called ``abelian ...

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.

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 ...

Cycles in algebraic systems [PDF]
Proceedings of the American Mathematical Society, 1956 2. Cycles and their terminology. Let L be an n Xn Latin square or, alternatively, let Q be a quasigroup of order n. Let M be the set of n2 ordered triplets ijk, where k is the entry in the ith row and jth column of L. If S is the set of n2 ordered pairs ij, and if rir: M->S is the projection parallel to the ith coordinate (for example, ir2(ijk) =ik ...
