Free Involutions on Homotopy (4&+3)-spheres
In [ l ] Browder and Livesay defined an invariant a(Tt 2 ) £ 8 Z of a free differentiate involution T of a homotopy (4&+3)-sphere 2 , k>0. I t is the precise obstruction to finding an invariant (4&+2)sphere of the involution. In [5] and [ô] Medrano showed how to construct free involutions with arbitrary Browder-Livesay invariant on some homotopy (4&+3) -spheres and hence that there exist infini...
متن کاملOn the homotopy groups of spheres in homotopy type theory
The goal of this thesis is to prove that π4(S) ' Z/2Z in homotopy type theory. In particular it is a constructive and purely homotopy-theoretic proof. We first recall the basic concepts of homotopy type theory, and we prove some well-known results about the homotopy groups of spheres: the computation of the homotopy groups of the circle, the triviality of those of the form πk(S) with k < n, and...
متن کاملLectures on Groups of Homotopy Spheres
Kervaire and Milnor's germinal paper [15], in which they used the newly-discovered techniques of surgery to begin the classification of smooth closed manifolds homotopy equivalent to a sphere (homotopy-spheres), was intended to be the first of two papers in which this classification would be essentially completed (in dimensions > 5). Unfortunately , the second part never appeared. As a result, ...
متن کاملSome Cyclic Group Actions on Homotopy Spheres
In [4J Orlik defined a free cyclic group action on a homotopy sphere constructed as a Brieskorn manifold and proved the following theorem: THEOREM. Every odd-dimensional homotopy sphere that bounds a para-llelizable manifold admits a free Zp-action for each prime p. On the other hand, it was shown ([3J) that there exists a free Zp-action on a 2n-1 dimensional homotopy sphere so that its orbit s...
متن کاملDifferentiable Z9 Actions on Homotopy Spheres
The results of [4] proved that many exotic spheres do not admit smooth actions of relatively high-dimensional compact Lie groups (all group actions considered in this paper are assumed to be effective). It was clear that stronger results should hold in certain cases, and this was confirmed in [5]. A notable feature of [5] is the use of nonexistence theorems for certain smooth circle actions to ...
