Preorder characterizations of lower separation axioms and their applications to foliations and flows
Tomoo Yokoyama
In this paper, we characterize several lower separation axioms , , , -space, nested, , , , and using pre-order. To analyze topo…
Graph representations of surface flows
Tomoo Yokoyama
We construct a complete invariant for non-wandering surface flows with finitely many singular points but without locally dense orbits. Precisely, we show that a flow with finit…
Decompositions of surface flows
Tomoo Yokoyama
Flows on surfaces are one of the most fundamental and classical objects in dynamical systems, and are studied from various areas (e.g. integrable systems, differential equations, f…
On low-codimensional decompositions
Tomoo Yokoyama
Decompositions on manifolds appear in various geometric structures. Necessary and sufficient conditions for quotient spaces of decompositions to be manifolds are widely characteriz…
