We consider geometric non-intersecting straight-line perfect matchings of $X_{2k}$. Two such matchings, $M$ and $M'$, are disjoint compatible if they do not have common edges, and no edge of $M$ crosses an edge of $M'$. Denote by $mathrm{DCM}_k$ the graph whose vertices ...
Anti-freezing refers to actions of lowering a freezing point, preventing ice formation or lowering a speed of ice formation, preventing ice recrystallization, lowering a speed of ice recrystallization, or maintaining a size of ice crystals to be small. As used herein, the term “anti-freezing”...
