## What is/are Rotating Periodic?

Rotating Periodic - The paper concerns the existence of rotating periodic solutions in Hamiltonian systems.^{[1]}We will study the multiplicity of rotating periodic solutions, i.

^{[2]}By introducing a new energy functional and employing the fountain theorem, the existence of infinitely many rotating periodic solutions is obtained.

^{[3]}We examine the role of the vortex structures particularly the counter-rotating periodic vortices generated from the leading and trailing edges of the inverted foil, and the interaction between them on the LAF.
