L-free directed bipartite graphs and echelon-type canonical forms, in the sense that it is unique. In , working within the context of the algebra . of upper triangular .×. matrices, certain new canonical forms of echelon-type have been introduced. Subalgebras of . determined by a pattern of zeros have been considered too. The issue there is whether or not those

An application of the Schur complement to truncated matricial power moment problems,lems. Using a special kind of Schur complement we obtain a more transparent insight into the nature of this phenomenon. In particular, a concrete general principle to describe it is obtained. This unifies an important aspect connected with truncated matricial moment problems.

Canonical form for ,-symplectic matrices,tic, that is, . = .. . canonical form for such pairs is derived under the transformations (.) → (. ., .) for invertible matrices .. In the canonical form for the pair, the matrix . is brought in standard (real or complex) Jordan normal form, in contrast to existing canonical forms.

A note on the Fredholm theory of singular integral operators with Cauchy and Mellin kernels,1) of the real axis ℝ is proved together with a respective Fredholm index formula. These operators are composed by the Cauchy singular integral operator, Mellin operators and operators of multiplication by piecewise continuous functions.
