چکیده
We attach copies of the circle to points a subset D separable metric space X and construct an earring E ( , ) . show that fundamental group is isomorphic subgroup Hawaiian group, if simply-connected locally simply-connected. In addition path-connected, can be recovered from

Homotopy Categories for Simply Connected Torsion Spaces
For each n > 1 and each multiplicative closed set of integers S, we study closed model category structures on the pointed category of topological spaces, where the class of weak equivalences are classes of maps inducing isomorphism on homotopy groups with coefficients in determined torsion abelian groups, in degrees higher than or equal to n. We take coefficients either on all the cyclic groups...
متن کاملInjectivity radius and Cartan polyhedron for simply connected symmetric spaces
We explore relationship between the cut locus of an arbitrary simply connected and compact Riemannian symmetric space and the Cartan polyhedron of corresponding restricted root system, and compute injectivity radius and diameter for every type of irreducible ones.
متن کاملOn digital simply connected spaces and manifolds: a digital simply connected 3-manifold is the digital 3-sphere
In the framework of digital topology, we study structural and topological properties of digital ndimensional manifolds. We introduce the notion of simple connectedness of a digital space and prove that if M and N are homotopy equivalent digital spaces and M is simply connected, then so is N. We show that a simply connected digital 2-manifold is the digital 2-sphere and a simply connected digita...
متن کاملSome results of semilocally simply connected property
If we consider some special conditions, we can assume fundamental group of a topological space as a new topological space. In this paper, we will present a number of theorems in topological fundamental group related to semilocally simply connected property for a topological space.
متن کاملOn Simply-connected 4-manifolds
This paper concerns (but does not succeed in performing) the diffeomorphism classification of closed, oriented, differential, simply-connected 4-manifolds. It arises out of the observation (due to Pontrjagin and Milnor [2]) that if two such manifolds Mx and M2 have isomorphic quadratic forms of intersection numbers on #2(Jft-), then there is a map / : M1-^-Mi which is a homotopy equivalence and...
