Isomorphism of cosymplectomorphism groups implies diffeomorphism of manifolds
Etienne Djoukeng, Stephane Tchuiaga
We prove that if two closed, connected, regular cosymplectic manifolds have isomorphic groups of cosymplectomorphisms (as topological groups), then the underlying manifolds are dif…

Cosymplectic Lagrangian-like submanifolds
S. Tchuiaga, F. Balibuno, E. Djoukeng
This paper highlights the similarities between even-dimensional geometry (symplectic) and odd-dimensional geometry (cosymplectic). We study the Lagrangian Grassmannian in the cosym…
