source: src/LIN/joint_LTL_LIN_semantics.ma @ 1784

Last change on this file since 1784 was 1451, checked in by sacerdot, 9 years ago
  1. All axioms in LIN/semantics.ma closed
  2. succ_pc and pointer_of_label moved to more_sem_params1; their type have been changed too to implement LIN/semantics.ma
