D-branes of A-type, their deformations, and Morse cobordism of A-branes on Calabi-Yau 3-folds under a split attractor flow: Donaldson/Alexander-Hilden-Lozano-Montesinos-Thurston/Hurwitz/Denef-Joyce meeting Polchinski-Grothendieck

In [L-Y5] (D(6): arXiv:1003.1178 [math.SG]) we introduced the notion of Azumaya C1-manifolds with a fundamental module and morphisms therefrom to a complex manifold. In the current sequel, we use this...
Rational knot concordance and homology cobordism
Rational knot concordance homology cobordism
2010/11/24
The following is a long-standing open question: "If the zero-framed surgeries on two knots in the 3-sphere are integral homology cobordant, are the knots themselves concordant?" We show that an obvio...
Models for $(\infty, n)$-categories and the cobordism hypothesis
the cobordism hypothesis math
2010/11/8
In this paper we introduce the models for $(\infty, n)$-categories which have been developed to date, as well as the comparisons between them that are known and conjectured. We review the role of $(\i...
On the relation of symplectic algebraic cobordism to hermitian K-theory
symplectic algebraic cobordism hermitian K-theory
2010/11/9
We reconstruct hermitian K-theory via algebraic symplectic cobordism. In the motivic stable homotopy category SH(S) there is a unique morphism g : MSp -> BO of commutative ring T- spectra which sends...
We construct algebraic cobordism spectra MSL and MSp. They are commutative monoids in the category of symmetric T^{2}- spectra. The spectrum MSp comes with a natural symplectic orientation given eithe...
We describe the equivariant cobordism ring of smooth toric varieties. This equivariant description is used to compute the ordinary cobordism ring of such varieties.
Chern-Simons invariants, SO(3) instantons, and Z/2-homology cobordism
Chern-Simons invariants SO(3) instantons Z/2-homology cobordism
2010/12/14
We review the SO(3) instanton gauge theory of Fintushel and Stern and recast it in the context of 4-manifolds with cylindrical ends. Appli-cations to the Z/2 homology cobordism group of Z/2 homology 3...
$\TT^2$-cobordism of Quasitoric 4-Manifolds
torus action quasitoric manifold cobordism group
2010/11/29
We show the T2-cobordism group of the category of 4-dimensional quasitoric manifolds is generated by the T2-cobordism class of CP2. The main tool is the theory of quasitoric manifolds.
