Differential Dynamic Logic
Brandon Bohrer
We formalize differential dynamic logic, a logic for proving properties of 
hybrid systems. The proof calculus in this formalization is based on the uniform 
substitution principle. We show it is sound with respect to our denotational 
semantics, which provides increased confidence in the correctness of the 
KeYmaera X theorem prover based on this calculus. As an application, we include 
a proof term checker embedded in Isabelle/HOL with several example proofs.
