Fundamental Classes in Algebraic Cobordism

We recall our construction of fundamental classes in the algebraic cobordism of smooth quasi-projective varieties, and show by examples that it is not possible to extend this to fundamental classes, functorial for local complete intersection morphisms, for Cohen-Macaulay varieties.

The Cobordism Group of Homology Cylinders

Garoufalidis and Levine introduced the homology cobordism group of homology cylinders over a surface. This group can be regarded as a generalization of the mapping class group. Using torsion invariants, we show that the abelianization of this group is infinitely generated provided that the first Betti number of the surface is positive. In particular, this shows that the group is not perfect. Th...

We compute the equivariant (stable) complex cobordism ring (MUG)∗ for finite abelian groups G.

Rigid String From QCD Lagrangian

Starting from the 4-dimensional gluodynamics, we discuss the statistical ensemble of torons (the toron is a self-dual solution with fractional topological number; it can be understood as a point defect) which interact strongly. It is shown that the effective Lagrangian describing this statistical ensemble possesses the fourth derivative kinetic term and leads to the area law for the Wilson loop...

Representations of the fundamental group of an l-punctured sphere generated by products of Lagrangian involutions

In this paper, we characterize unitary representations of π := π1(S \{s1, . . . , sl}) whose generators u1, . . . , ul (lying in conjugacy classes fixed initially) can be decomposed as products of two Lagrangian involutions uj = σjσj+1 with σl+1 = σ1 . Our main result is that such representations are exactly the elements of the fixed-point set of an anti-symplectic involution defined on the mod...
