Abstract
Let Q be a nondegenerate quadratic form and L a nonzero linear form of dimension d > 3. As a generalization of the Oppenheim conjecture, we prove that the set {(Q(x); L(x)) : x is an element of Z(d)} is dense in R-2 provided that Q and L satisfy some natural conditions. The proof uses dynamics on homogeneous spaces of Lie groups.
