The 1-type of a Waldhausen K-theory spectrum
(Elsevier, 2007-12-01)We give a small functorial algebraic model for the 2-stage Postnikov section of the K-theory spectrum of a Waldhausen category and use our presentation to describe the multiplicative structure with respect to biexact functors.

The algebra of secondary homotopy operations in ring spectra
(London Mathematical Society, 2011)The primary algebraic model of a ring spectrum R is the ring π∗R of homotopy groups. We introduce the secondary model π∗,∗R ...

The analytic standard fan of a D-module
(Elsevier, 2001-10-24)We extend to the analytic D-module case our results in the algebraic case, namely, we associate with any monogeneous module ...

The characteristic cohomology class of a triangulated category
(2005)The concept of a triangulated homotopy category can be canonically lifted to the level of a groupoid-enriched category. This way two natural axioms on track triangles replace the four somewhat obscure axioms of a triangulated category.

The nth root of a braid is unique up to conjugacy
(Mathematical Sciences Publishers, 2003-11-01)We prove a conjecture due to Makanin: if α and β are elements of the Artin braid group Bn such that α k = β k for some nonzero integer k, then α and β are conjugate. The proof involves the Nielsen-Thurston classification of braids.
