final class USubstAboveURen extends RenUSubstBase
Renaming Uniform Substitution that, in Sequent direction, first runs a uniform renaming and on the result subsequently the uniform substituion.
s(RG) |- s(RD) -------------- USubst RG |- RD -------------- URen G |- D
- Note
reading in Hilbert direction from top to bottom, the uniform substitution comes first to ensure the subsequent uniform renaming no longer has nonrenamable program constants since no semantic renaming.

KeYmaera X: An aXiomatic Tactical Theorem Prover
KeYmaera X is a theorem prover for differential dynamic logic (dL), a logic for specifying and verifying properties of hybrid systems with mixed discrete and continuous dynamics. Reasoning about complicated hybrid systems requires support for sophisticated proof techniques, efficient computation, and a user interface that crystallizes salient properties of the system. KeYmaera X allows users to specify custom proof search techniques as tactics, execute tactics in parallel, and interface with partial proofs via an extensible user interface.
