Triangular type ordered subalgebras in a column model
The paper deals with directed partially ordered real linear associative algebras satisfying the Dedekind sigma complete condition, especially with the so-called column models. If such an algebra has a multiplicative diagonal projection map then it is called triangular. The main result of the paper is the characterization of order-convex triangular subalgebras of column algebras.
