Finding classes of delta-matroids closed under handle slides
Rémi Cocou Avohou
In this work, we study the operations of handle slides introduced recently for delta-matroids by Iain Moffatt and Eunice Mphako-Banda. We then prove that the class of binary delta-…

Polynomial Invariants for Arbitrary Rank Weakly-Colored Stranded Graphs
Remi Cocou Avohou
Polynomials on stranded graphs are higher dimensional generalization of Tutte and Bollobás-Riordan polynomials [Math. Ann. 323 (2002), 81-96]. Here, we deepen the analysis of the p…

On terminal forms for topological polynomials for ribbon graphs: The -petal flower
Remi C. Avohou, Joseph Ben Geloun, Etera R. Livine
The Bollobas-Riordan polynomial [Math. Ann. 323, 81 (2002)] extends the Tutte polynomial and its contraction/deletion rule for ordinary graphs to ribbon graphs. Given a ribbon grap…
