Regular octagons in Poincare model of Lobachevsky geometry
Oleksandr Pryshliak
To investigate the topological structure of Morse flows on the 2-disk we use the planar graphs as destinguished graph of the flow. We assume, that the flow is transversal to the bo…

Planar trees as complete topological invariants of Morse flows with a sink on the 2-sphere
Oleksandr Pryshliak
To investigate the topological structure of Morse flows with a sink on the 2-sphere we use the planar tree as complete topological invariant of the flow. We give a list of all plan…
