Abstract
Multinets are certain configurations of lines and points with multiplicities in the complex projective plane P2. They are used in the studies of resonance and characteristic varieties of complex hyperplane arrangement complements and cohomology of Milnor fibers. From combinatorics viewpoint they can be considered as generalizations of Latin squares. Very few exam- ples of multinets with non-trivial multiplicities are known. In this paper, we present new examples of multinets. These are obtained by using an analogue of nets in P3 and intersecting them by planes.
