2 3 Se p 19 99 QUANTIZED RANK R MATRICES

First some old as well as new results about P.I. algebras, Ore extensions, and degrees are presented. Then quantized n × r matrices as well as quantized factor algebras of M q (n) are analyzed. The latter are the quantized function algebra of rank r matrices obtained by working modulo the ideal generated by all (r + 1) × (r + 1) quantum subdeterminants and a certain localization of this algebra...

2 00 3 Uniform chains of small transfinite rank

We extend F.Pastjin's construction of uniform decomposable chains of finite rank to those of rank 'finite over a limit' and investigate infinite (length ω) products and unions of such chains. We derive an extension of Pastjin's characterisation to uniform decomposable chains of small transfinite rank (≤ ω + ω).

Geometry of Rank 2

A notion of a Frobenius manifold with a nice real structure was introduced by Hertling. It is called CDV structure (Cecotti-Dubrovin-Vafa structure). In this paper, we introduce a “positivity condition” on CDV structures and show that any Frobenius manifold of rank two with real spectrum can be equipped with a positive CDV structure. We extend naturally the symmetries of Frobenius structures gi...

2 Edmonds ’ Algorithm for Maximum Matching 3 Minimum Edge Covers

Any set of vertices V ′ with {{u, v} : u ∈ V ′} (smallest or otherwise) is called a vertex cover of the graph. Intuitively, a cover is a dusting of vertices so that every edge in the graph is “covered” by some vertex, although you might also say that each edge is “hit” by some vertex. Note that vertex cover is a minimization problem, with the goal to find a vertex cover that is as small as poss...
