Entity: Moser’s stability theorem
Triple: [Introduction to Symplectic Topology, topic, Moser’s stability theorem]

Moser’s stability theorem is a fundamental result in symplectic geometry that guarantees, under suitable conditions, the existence of a diffeomorphism relating smoothly varying volume or symplectic forms, showing that such structures are locally unique up to isotopy.
