Extreme diagonally and antidiagonally symmetric alternating sign matrices of odd order [PDF]
Advances in Mathematics, 2016 For each $\alpha \in \{0,1,-1\}$, we count alternating sign matrices that are invariant under reflections in the diagonal and in the antidiagonal (DASASMs) of fixed odd order with a maximal number of $\alpha$'s along the diagonal and the antidiagonal, as

The Fate of the Landau Levels under Perturbations of Constant Sign
, 2009 We show that the Landau levels cease to be eigenvalues if we perturb the 2D Schr\"odinger operator with constant magnetic field, by bounded electric potentials of fixed sign.

Procedural embodiment and magic in linear equations [PDF]
, 2008 How do students think about algebra? Here we consider a theoretical framework which builds from natural human functioning in terms of embodiment – perceiving the world, acting on it and reflecting on the effect of the actions – to shift to the use of ...

Alternating sign matrices and hypermatrices, and a generalization of Latin squares [PDF]
Advances in Applied Mathematics, 2017 An alternating sign matrix, or ASM, is a $(0, \pm 1)$-matrix where the nonzero entries in each row and column alternate in sign. We generalize this notion to hypermatrices: an $n\times n\times n$ hypermatrix $A=[a_{ijk}]$ is an {\em alternating sign ...

Triangle or tripod? Neither: A diagrammatic investigation into a sign’s visual representation
Sign Systems StudiesThis paper takes a look at the morphological structure of the two dominant diagrams (the triangle and the tripod) used in semiotic literature to represent the irreducible triadic sign of C. S. Peirce in order to evaluate their diagrammatic aptitude, i.e.
