Variational principles analogous to classical ones are exhibited for the eigenvalues of Ax - lambda 2 Bx - lambda x 0, where A and B are compact, positive operators in a Hilbert space. Unlike the classical ones, they involve a nonquadratic form and both nonlinear and linear auxiliary conditions. Author
