  Modal interpretations constitute another class of no-collapse interpretations of quantum mechanics that were developed to reconcile quantum mechanics with relativity (and to solve the measurement problem). Yet, as the no-go theorems by Dickson and Clifton (1998), Arntzenius (1998) and Myrvold (2002) demonstrate, the earlier versions of the modal interpretation are not genuinely compatible with relativity theory. Further, Earman and Ruetsche (2005) argue that a quantum-field version of the modal interpretation (which is set in the context of relativistic quantum-field theory), like the one proposed by Clifton (2000), would be subject to serious challenges.  Berkovitz and Hemmo (2006a,b) develop a relational modal interpretation that escapes all the above no-go theorems and to that extent seems to provide better prospects for reconciling quantum mechanics with special relativity.
