Seitz and Stackelberg on Oligopoly.
No full textThis essay deals with the contribution of Seitz and Stackelberg on oligopoly. Stackelberg's theory on price leadership has been taken up by Seitz in his dissertation of 1965. The author summarizes the debate in Germany in the beginning of the sixties on oligopoly theory between Krelle, Ott, Heertje, Helmstadter und Seitz. He looks back from a game theoretical point of view.oligopoly, Nash-equilibrium, Stackelberg, Seitz, Krelle, game theory, Cournot, two-period game, one-shot game
Wigner-Seitz Cell generation and calculations in MATLAB
No full textVoronoi (Wigner-Seitz) cells and related calculations can be performed using VoronoiTesselation.m. The code is heavily commented with instructions included. Sample .xtl structure files exported from Vesta are included for various crystals and are readily loaded into the program.
2D diffraction patterns can be simulated using the associated diffraction.m script. The angle of the structure relative to an incident beam is readily changed and various structures can be examined using the same structure loading algorithms used for VoronoiTesselation.m. See link to index 1D SAXS data: https://hdl.handle.net/11299/223278This series of MATLAB codes was developed to generate publication-quality Wigner-Seitz cells for a variety of structures. These are frequently desired for self-assembled micellar systems, wherein the geometry of the Wigner-Seitz cell plays a role in the emergence of several packings. The main algorithm (VoronoiTesselation.m) is generalized, allowing specification of lattice positions and parameters or the upload of these values from a .xtl file exported from Vesta. Added is the ability to determine various cell parameters, including the coordination number, area/volume, and the second-moment volume, which is proportional to the stretching moment for polymer chains stretched from the cell center to the cell edges. A simple algorithm for simulation of 2D diffraction patterns is also included (diffraction.m).NSF DMR-1801993NSF GRFP-00039202Lindsay, Aaron P; Mueller, Andreas J; Mahanthappa, Mahesh K; Lodge, Timothy P; Bates, Frank S.

Residue symbols and Jantzen-Seitz partitions
No full text. Jantzen-Seitz partitions are those p-regular partitions of n which label p-modular irreducible representations of the symmetric group S n which remain irreducible when restricted to S n\Gamma1 ; they have recently also been found to be important for certain exactly solvable models in statistical mechanics. In this article we study their combinatorial properties via a detailed analysis of their residue symbols; in particular the p-cores of Jantzen-Seitz partitions are determined. 1 Introduction The Mullineux symbols are combinatorial objects which were introduced in order to understand the following question in the modular representation theory of the symmetric groups S n , n a natural number. For a given prime p the p-modular irreducible representations D of S n are labeled in a canonical way by the p-regular partitions of n. When the modular irreducible representation D of S n is tensored by the sign representation we get a new modular irreducible representation D P . ..
