The Kauffman bracket skein module of a twist knot exterior.
The Kauffman bracket skein module of S1 x S2.
The Kazhdan property of the mapping class group of closed surfaces and the first cohomology group of its cofinite subgroups.
The Kervaire invariant of immersions.
The Kevaire Invariant of Hypersurfaces in Complex Projective Spaces.
The Kontsevich integral and quantized Lie superalgebras.
The Kontsevich integral and re-normalized link invariants arising from Lie superalgebras
We show that the coefficients of the re-normalized link invariants of [3] are Vassiliev invariants which give rise to a canonical family of weight systems.

The L²-invariants and Morse numbers
We study the homotopy invariants of free cochain complexes and Hilbert complexes. These invariants are applied to calculation of exact values of Morse numbers of smooth manifolds.

The Lyusternik-Shnirel'man category, vector bundles, and immersions of manifolds.
The Łojasiewicz gradient inequality in a neighbourhood of the fibre
Some estimates of the Łojasiewicz gradient exponent at infinity near any fibre of a polynomial in two variables are given. An important point in the proofs is a new Charzyński-Kozłowski-Smale estimate of critical values of a polynomial in one variable.
