Maximal harmonic group actions on finite graphs
This paper studies groups of maximal size acting harmonically on a finite graph. Our main result states that these maximal graph groups are exactly the finite quotients of the modular group Γ = 〈 x, y | x = y = 1 〉 of size at least 6. This characterization may be viewed as a discrete analogue of the description of Hurwitz groups as finite quotients of the (2, 3, 7)-triangle group in the context...
متن کاملFinite Group Actions on P ” ( C )
Consider the question: which finite groups operate as symmetries of the complex projective plane P’(C)? Any finite subgroup of &X,(C) acts as a group of collineations and these give the linear models. The list of such groups is relatively short [MBD] but contains, for example, a groups of rank < 2, subgroups of U(Z), and the simple groups A,, A,, an PSL(F,). It turns out that these linear group...
متن کاملFinite Group Actions on Kervaire Manifolds
Let M K be the Kervaire manifold: a closed, piecewise linear (PL) manifold with Kervaire invariant 1 and the same homology as the product S × S of spheres. We show that a finite group of odd order acts freely on M K if and only if it acts freely on S × S. If MK is smoothable, then each smooth structure on MK admits a free smooth involution. If k 6= 2 − 1, then M K does not admit any free TOP in...
متن کاملFinite Group Actions on Siegel Modular Spaces
The theory of nonabelian cohomology is used to show that the set of fixed points of a finite group acting on a Siegel modular space is a union of Shimura varieties
متن کاملSzegö Kernels and Finite Group Actions
Let (M,ω) be a compact symplectic manifold of dimension 2n, such that [ω] ∈ H(M,Z). Fix J ∈ J (M,ω) (the contractible space of all almost complex structures on M compatible with ω), and let h and g = R(h) be the induced hermitian and riemannian structures. There exist an hermitian line bundle (A, h) on M and a unitary covariant derivative ∇A on A, such that −2πiω is the curvature of ∇A. In this...
