Minimization problems for noncoercive functionals subject to constraints. II
This is a continuation of Part I [Trans. Am. Math. Soc. 347, 4485-4513 (1995; Zbl 0849.35040)] concentrating on the Hilbert case. The existence of Landesman-Lazer type is proved for semilinear elliptic equations and noncoercive semilinear variational inequalities. Applications to critical point theory are also given.
