A New Characterization of Generalized Complementary Basic Matrices
In this paper, a new characterization of previously studied generalized complementary basic matrices is obtained. It is in terms of ranks and structure ranks of submatrices defined by certain diagonal positions. The results...

The generic rank of A–planar structures.
The paper mostly collects material on generic rank of A–modules with respect to differential geometric applications. Our research was motivated by geom- etry of A–structures. In particular, we discuss the case of A being an unitary...

Rapidity-rank structure of pp - pairs hadronic Z 0 decays.
In this paper, a novel method, using the rapidity-rank structure of pp pairs, is used to study the mechnaism of baryon production in hadronic Zo decay....

A note on monotone complexity and the rank of matrices.
. Wedescribe a simple condition on combinatorial structures, such that the rank ofthe matrix associated with these structures gives lower bounds on monotone span program size and monotone formula size. We also prove an uppe...

Some structural properties of low rank matrices related to computational complexity.
We consider the problem of the presence of short cycles in the graphs of nonzero elements of matrices which have sublinear rank and nonzero entries on the main diagonal, and analyze the connection between these properties and the rigidity of...

Effect of the microporous structure of coals on their swelling in the organic solvents.
Eight coals of various genetic types on reduction degree were investigated. The distinction of their microporous structure inside one rank are shown. The effect of coal microporosity on character on their swelling in DMFA was establ...
