Interlacement and Activities in Delta-Matroids
Ada Morse
We generalize theories of graph, matroid, and ribbon-graph activities to delta-matroids. As a result, we obtain an activities based feasible-set expansion for a transition polynomi…

DNA Origami and Unknotted A-trails in Torus Graphs
Ada Morse, William Adkisson, Jessica Greene +4
Motivated by the problem of determining unknotted routes for the scaffolding strand in DNA origami self-assembly, we examine existence and knottedness of A-trails in graphs embedde…
