Nonexistence results for Hadamard-like matrices.
Non-integer lattice tilings by (k, n) truncated crosses.
Non-intersecting, simple, symmetric random walks and the extended Hahn kernel
We show using non-intersecting paths, that a random rhombus tiling of a hexagon, or a boxed planar partition, is described by a determinantal point process given by an extended Hahn kernel.
