Set-theoretic Yang-Baxter cohomology of cyclic biquandles
Minyi Liang, Xiao Wang, Seung Yeop Yang
We completely determine the free parts of the set-theoretic Yang-Baxter (co)homology groups of finite cyclic biquandles, along with fully computing the torsion subgroups of their 1…
The geometric realization of a normalized set-theoretic Yang-Baxter homology of biquandles
Xiao Wang, Seung Yeop Yang
Biracks and biquandles, which are useful for studying the knot theory, are special families of solutions of the set-theoretic Yang-Baxter equation. A homology theory for the set-th…
Set-theoretic Yang-Baxter (co)homology theory of involutive non-degenerate solutions
Józef H. Przytycki, Petr Vojtěchovský, Seung Yeop Yang
W. Rump showed that there exists a one-to-one correspondence between involutive right non-degenerate solutions of the Yang-Baxter equation and Rump right quasigroups. J. S. Carter,…
A prismatic classifying space
J. Scott Carter, Victoria Lebed, Seung Yeop Yang
A qualgebra is a set having two binary operations that satisfy compatibility conditions which are modeled upon a group under conjugation and multiplication. We develop a homolo…
Rooted trees with the same plucking polynomial
Zhiyun Cheng, Sujoy Mukherjee, Jozef Przytycki +2
In this paper we give a sufficient and necessary condition for two rooted trees with the same plucking polynomial. Furthermore, we give a criteria for a sequence of non-negative in…
Search for torsion in Khovanov homology
Sujoy Mukherjee, Józef H. Przytycki, Marithania Silvero +2
In the Khovanov homology of links, presence of -torsion is a very common phenomenon. Finite number of examples of knots with -torsion for were als…
Extended quandle spaces and shadow homotopy invariants of classical links
Seung Yeop Yang
In 1993, Fenn, Rourke and Sanderson introduced rack spaces and rack homotopy invariants, and modifications to quandle spaces and quandle homotopy invariants were introduced by Nosa…
Annihilation of torsion in homology of finite -AQ quandles
Józef H. Przytycki, Seung Yeop Yang
It is a classical result in reduced homology of finite groups that the order of a group annihilates its homology. Similarly, we have proved that the torsion subgroup of rack and qu…
Twist Spinning Knotted Trivalent Graphs
J. Scott Carter, Seung Yeop Yang
In 1965, E. C. Zeeman proved that the (+/-)-twist spin of any knotted sphere in (n-1)-space is unknotted in the n-sphere. In 1991, Y. Marumoto and Y. Nakanishi gave an alternate pr…
The torsion of a finite quasigroup quandle is annihilated by its order
Jozef H. Przytycki, Seung Yeop Yang
We prove that if Q is a finite quasigroup quandle, then |Q| annihilates the torsion of its homology. It is a classical result in reduced homology of finite groups that the order of…
