Affine Configurations of 4 Lines in R R R 3
We prove that affine configurations of 4 lines in R3 are topologically and combinatorially homeomorphic to affine configurations of 6 points in R4.
متن کاملSmall Forbidden Configurations II
The present paper continues the work begun by Anstee, Griggs and Sali on small forbidden configurations. In the notation of (0,1)-matrices, we consider a (0,1)-matrix F (the forbidden configuration), an m × n (0,1)-matrix A with no repeated columns which has no submatrix which is a row and column permutation of F , and seek bounds on n in terms of m and F . We give new exact bounds for some 2× ...
متن کامل(k, r)-ADMISSIBLE CONFIGURATIONS AND INTERTWINING OPERATORS
Certain combinatorial bases of Feigin-Stoyanovsky’s type subspaces of level k standard modules for affine Lie algebra sl(r, C)̃ are parametrized by (k, r)-admissible configurations. In this note we use Capparelli-LepowskyMilas’ method to give a new proof of linear independence of these bases, the main ingredient in the proof being the use of Dong-Lepowsky’s intertwining operators for fundamental...
متن کاملOn Electro-kinetic Fluids: One Dimensional Configurations
Electro-kinetic fluids can be modeled by hydrodynamic systems describing the coupling between fluids and electric charges. The system consists of a momentum equation together with transport equations of charges. In the dynamics, the special coupling between the Lorentz force in the velocity equation and the material transport in the charge equation gives an energy dissipation law. In stationary...
متن کاملGenerating ensembles of two-dimensional granular configurations.
Dense granular materials, like glasses, exhibit slowing dynamics as they approach the jamming transition from a liquidlike state. In this video submission to the Gallery of Nonlinear Images, we visualize the effect of the packing fraction on the dynamics of a dense two-dimensional granular material floating in a single layer on a horizontal air table. From digital images, we track the positions...
