The fundamental group of the real moduli spaces M 0,n. A preliminary report on the topological aspects of some real algebraic varieties
نویسنده
چکیده
We prove that the fundamental group of the space of the real points of M0,n(C) is nonabelian (Theorem 14). The technique has a topological nature. Also, we prove that these spaces are non-orientable manifolds (Theorem 16). To our knowledge, the results are new.In a forthcoming manuscript, we investigate the associated combinatorial structures. Many of them were already studied in Computational Biology.

The Moduli Space of Stable Vector Bundles over a Real Algebraic Curve
We study the spaces of stable real and quaternionic vector bundles on a real algebraic curve. The basic relationship is established with unitary representations of an extension of Z/2 by the fundamental group. By comparison with the space of real or quaternionic connections, some of the basic topological invariants of these spaces are calculated.
متن کاملSemi-topological K-theory of Real Varieties
The semi-topological K-theory of real varieties, KR(−), is an oriented multiplicative (generalized) cohomology theory which extends the authors’ earlier theory, K(−), for complex algebraic varieties. Motivation comes from consideration of algebraic equivalence of vector bundles (sharpened to real semi-topological equivalence), consideration of Z/2-equivariant mapping spaces of morphisms of alge...
متن کاملAlgebraic and topological aspects of quasi-prime ideals
In this paper, we define the new notion of quasi-prime ideal which generalizes at once both prime ideal and primary ideal notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which admits the Zariski topology as a subspace topology. The basic properties of the quasi-prime spectrum are studied and several interesting results are obtained. Specially, it is pro...
متن کاملON THE CAPACITY OF EILENBERG-MACLANE AND MOORE SPACES
K. Borsuk in 1979, at the Topological Conference in Moscow, introduced concept of the capacity of a compactum and asked some questions concerning properties of the capacity ofcompacta. In this paper, we give partial positive answers to three of these questions in some cases. In fact, by describing spaces homotopy dominated by Moore and Eilenberg-MacLane spaces, the capacities of a Moore space $...
متن کاملSome Characterizations of Hopf Group on Fuzzy Topological Spaces
In this paper, some fundamental concepts are given relating to fuzzytopological spaces. Then it is shown that there is a contravariant functorfrom the category of the pointed fuzzy topological spaces to the category ofgroups and homomorphisms. Also the fuzzy topological spaces which are Hopfspaces are investigated and it is shown that a pointed fuzzy toplogicalspace having the same homotopy typ...
