On higher analogs of topological complexity
Farber introduced a notion of topological complexity \TC(X) that is related
to robotics. Here we introduce a series of numerical invariants \TC_n(X),
n=1,2, ... such that \TC_2(X)=\TC(X) and \TC_n(X)\le \TC_{n+1}(X). For
these higher complexities, we define their symmetric versions that can also be
regarded as higher analogs of the symmetric topological complexity.Comment: LATEX, 8 page
On analytical applications of stable homotopy (the Arnold conjecture, critical points)
We prove the Arnold conjecture for closed symplectic manifolds with
and \cat M=\dim M. Furthermore, we prove an analog of the
Lusternik-Schnirelmann theorem for functions with ``generalized hyperbolicity''
property.Comment: AMSTEX, 12 pages, submitted to Math. Zeitschrift, improvement
(correction) of the line of the proof of the Arnold conjectur
On Thom spaces, Massey products and non-formal symplectic manifolds
In this work we analyze the behavior of Massey products of closed manifolds
under the blow-up construction. The results obtained in the article are applied
to the problem of constructing closed symplectic non-formal manifolds. The
proofs use Thom spaces as an important technical tool. This application of Thom
spaces is of conceptual interest.Comment: 16 pages, amstex, changes according to the referee suggestions.
