## Abstract The following theorem is proved: Let __G__ be a graph of even order. Assume that there exists a connected spanning subgraph __F__ of __G__ such that for every set __U__ of four vertices in __G__, if the subgraph of __F__ induced by __U__ is a star, then the subgraph of __G__ induced by
## Abstract We consider the Signorini problem with Coulomb friction in elasticity. Sufficient conditions of nonβuniqueness are obtained for the continuous model. These conditions are linked to the existence of real eigenvalues of an operator in a Hilbert space. We prove that, under appropriate cond
