Trapezodial property of the generalized Alexander polynomial
Tamás Kálmán, Karola Mészáros, Alexander Postnikov
Fox's conjecture from 1962, that the absolute values of the coefficients of the Alexander polynomial of an alternating link are trapezoidal, has remained stubbornly open to this da…
Defect Positioning in Combinatorial Metamaterials
Chaviva Sirote-Katz, Yotam M. Y. Feldman, Guy Cohen +2
Combinatorial mechanical metamaterials are made of anisotropic, flexible blocks, such that multiple metamaterials may be constructed using a single block type, and the system's res…
Breaking Mechanical Holography in Combinatorial Metamaterials
Chaviva Sirote-Katz, Ofri Palti, Naomi Spiro +2
Combinatorial mechanical metamaterials are made of anisotropic, flexible blocks, such that multiple metamaterials may be constructed using a single block type, and the system's res…
Graph minors, Ehrhart theory, and a monotonicity property
Tamás Kálmán, Lilla Tóthmérész
We study the extended root polytope associated to a directed graph. We show that under the operations of deletion and contraction of an edge of the graph, none of the coefficients…
On Fox's trapezoidal conjecture
Soheil Azarpendar, András Juhász, Tamás Kálmán
We investigate Fox's trapezoidal conjecture for alternating links. We show that it holds for diagrammatic Murasugi sums of special alternating links, where all sums involved have l…
Homotopy classification of knotted defects in ordered media
Yuta Nozaki, Tamás Kálmán, Masakazu Teragaito +1
We give a homotopy classification of the global defects in ordered media, and explain it via the example of biaxial nematic liquid crystals, i.e., systems where the order parameter…
