A sharp sparse domination of pseudodifferential operators
Ryosuke Yamamoto
In this paper, we give a sharp sparse domination of pseudodifferential operators associated with symbols belonging to the Hörmander class, and fundamental solutions of dispersive e…
Partitions of cyclic words and Goldman-Turaev Lie bialgebra
Ryosuke Yamamoto
The free -module generated from the set of non-trivial homotopy classes of closed curves on an oriented surface has the structure of Lie bialgebra by two operations, th…
Geometric intersection number of simple closed curves on a surface and symplectic expansions of free groups
Ryosuke Yamamoto
For two oriented simple closed curves on a compact orientable surface with a connected boundary we introduce a simple computation of a value in the first homology group of the surf…
Open books supporting overtwisted contact structures and Stallings twist
Ryosuke Yamamoto
We study open books (or open book decompositions) of a closed oriented 3-manifold which support overtwisted contact structures. We focus on a simple closed curve along which one ca…
Almost alternating diagrams and fibered links in S^3
Hiroshi Goda, Mikami Hirasawa, Ryosuke Yamamoto
Let be an oriented link with an alternating diagram . It is known that is a fibered link if and only if the surface obtained by applying Seifert's algorithm to i…
