Partial-dual genus polynomial as a weight system
Sergei Chmutov
We prove that the partial-dual genus polynomial considered as a function on chord diagrams satisfies the four-term relation. Thus it is a weight system from the theory of Vassiliev…
On a conjecture of Gross, Mansour and Tucker
Sergei Chmutov, Fabien Vignes-Tourneret
Partial duality is a duality of ribbon graphs relative to a subset of their edges generalizing the classical Euler-Poincare duality. This operation often changes the genus. Recentl…
Decision-making in Livestock Biosecurity Practices amidst Environmental and Social Uncertainty: Evidence from an Experimental Game
Scott C. Merrill, Christopher J. Koliba, Susan M. Moegenburg +7
Livestock industries are vulnerable to disease threats, which can cost billions of dollars and have substantial negative social ramifications. Losses are mitigated through increase…
Cartan Prolongation of a Family of Curves Acquiring a Node
Susan Jane Colley, Gary Kennedy
Using the monster/Semple tower construction, we study the structure of the Cartan prolongation of the family of plane curves with nodal central member.
Turaev genus and alternating decompositions
Cody W. Armond, Adam M. Lowrance
We prove that the genus of the Turaev surface of a link diagram is determined by a graph whose vertices correspond to the boundary components of the maximal alternating regions of…
Entropy and thermopower in the 2D t-J model
W. O. Putikka
The entropy of the two-dimensional - model is investigated using its 12th order high temperature series. A direct Padé extrapolation of the entropy series doesn't converge we…
