We discuss the diagrammatic theory of knot isotopies in dimension 4. We project a knotted surface to a three-dimensional space and arrange the surface to have generic singularities upon further projection to a plane. We examine the singularities in this plane as an isotopy is performed, and give a f

In 1980, Piere Duchet conjectured that odd-directed cycles are the only edge minimal kernel-less connected digraphs, i.e. in which after the removal of any edge a kernel appears. Although this conjecture was disproved recently by Apartsin et al. (1996), the following modification of Duchet's conject

It is proved that non-linear systems with positive impulse functions satisfy the Aizerman conjecture in the input-output version. Besides, the stability criteria are formulated in the terms of the Hurwitzness of corresponding polynomials. In addition, new positivity conditions for impulse functions
