When the theories meet: Khovanov homology as Hochschild homology of links
Jozef H. Przytycki
We show that Khovanov homology and Hochschild homology theories share common structure. In fact they overlap: Khovanov homology of a -torus link can be interpreted as a Hoch…
Braids, Transversal links and the Khovanov-Rozansky Theory
Hao Wu
We establish some inequalities about the Khovanov-Rozansky cohomologies of braids. These give new upper bounds of the self-linking numbers of transversal links in standard contact…
Turing Degrees of Isomorphism Types of Algebraic Objects
Wesley Calvert, Valentina Harizanov, Alexandra Shlapentokh
The Turing degree spectrum of a countable structure is the set of all Turing degrees of isomorphic copies of . The Turing degree of the isomorphism type…
Torsion in Graph Homology
Laure Helme-Guizon, Jozef H. Przytycki, Yongwu Rong
Khovanov homology for knots has generated a flurry of activity in the topology community. This paper studies the Khovanov type cohomology for graphs with a special attention to tor…
Braid Family Representatives
Slavik Jablan, Radmila Sazdanovic
After defining reduced minimum braid word and criteria for a braid family representative, different braid family representatives are derived, and a correspondence between them and…
Measurement of the reaction gamma p --> K0 Sigma+ at photon energies up to 2.6 GeV
R. Lawall, J. Barth, C. Bennhold +14
The reaction gamma p --> K0 Sigma+ was measured in the photon energy range from threshold up to 2.6 GeV with the SAPHIR detector at the electron stretcher facility, ELSA, in Bonn.…
