Let be a real number satisfying . We denote by the configuration space of regular spherical -gons with side-lengths . The purpose of this paper is to dete…
On the middle dimensional homology classes of equilateral polygon spaces
Yasuhiko Kamiyama
Let be the configuration space of equilateral polygonal linkages with vertices in the Euclidean plane . We consider the case that is odd and set $n=2m+…
The homology of spaces of polynomials with roots of bounded multiplicity
Yasuhiko Kamiyama
Let P_{k, n}^l be the space consisting of monic complex polynomials f(z) of degree k and such that the number of n-fold roots of f(z) is at most l. In this paper, we determine the…
Configurations and parallelograms associated to centers of mass
F R Cohen, Yasuhiko Kamiyama
The purpose of this article is to 1. define M(t,k) the t-fold center of mass arrangement for k points in the plane, 2. give elementary properties of M(t,k) and 3. give consequences…
Spaces of real polynomials with common roots
Yasuhiko Kamiyama
Let RX_{k,n}^l be the space consisting of all (n+1)-tuples (p_0(z),...,p_n(z)) of monic polynomials over R of degree k and such that there are at most l roots common to all p_i(z).…
The Chow ring of the moduli space and its related homogeneous space of bundles on P^2 with charge 1
Yasuhiko Kamiyama, Michishige Tezuka
For an algebraically closed field K with ch K \not = 2, we determine the Chow ring of the moduli space of holomorphic bundles on a projective plane with the structure group SO(n,K)…
