摘要

On a closed orientable surface M_g~2 of genus g, we consider the foliation of a weakly generic Morse form ω on M_g~2 and show that for such forms c(ω) + m(ω) = g ? (1/2)k(ω), where c(ω) is the number of homologically independent compact leaves of the foliation, m(ω) is the number of its minimal components, and k(ω) is the total number of singularities of ω that are surrounded by a minimal component. We also give lower bounds on m(ω) in terms of k(ω) and the form rank rk ω or the structure of ker [ω], where [ω] is the integration map.
