Webthe representability of the bi-uniform matroid over finite fields. Observe that the value of this parameter is the same for a bi-uniform matroid M and for its dual M∗. If d = 0, then the problem reduces to the representability of the uniform matroid. Similarly, if d = 1 then, by adding to S ∪ T a nonzero vector in the one-dimensional WebF. N-Representability G.

Piris 22.1 Introduction The purpose of this chapter is to analyze the role of the N-representability … WebThe subject of my PhD dissertation was quantum computation, including topics in quantum random walks, cavity quantum electrodynamics, spin physics, and the N-representability problem. From 2005-2010, I worked as a postdoctoral associate with Prof. John Tully at Yale where I did research into nonadiabatic dynamics, electron transfer, and surface science. Web20 jul. 2012 · In [ J. Math. Phys. 13, 1608–1621 (1972)], Erdahl considered the convex structure of the set of N -representable 2-body reduced density matrices in the case of fermions. Some of these results have a straightforward extension to the m -body setting and to the more general quantum marginal problem. elemental witches mod 1.7.10
