Matveev, S. V.; Fomenko, A. T.; Sharko, V. V. Round Morse functions and isoenergy surfaces of integrable Hamiltonian systems. (English. Russian original) Zbl 0673.58023 Math. USSR, Sb. 63, No. 2, 319-336 (1989); translation from Mat. Sb., Nov. Ser. 135(177), No. 3, 325-345 (1988). A connection between a topological classification of 3-dimensional manifolds and a symplectic topology of integrable Hamiltonian systems is discovered and studied. In particular an equivalence of a class (S) of 3- dimensional closed compact manifolds with a smooth function whose critical point set consists of nondegenerate circles, a class (H) of irreducible closed isoenergetic manifolds of integrable Hamiltonian systems and a class of irreducible closed manifolds possessing circular Morse function is proved. An explicit condition for the existence of minimal circular Morse function on connected closed manifold \(M^ n\), \(n\geq 6\) is given.
