Title: Translating Scala programs to Isabelle with Leon
Speaker: Lars Hupel
Abstract:

Leon is a system for verifying functional Scala programs. It uses a variety  
of automated theorem provers (ATPs) to check verification conditions (VCs)  
stemming from the input program. This process is completely automatic: no  
user intervention is required for proving these conditions. Isabelle, on  
the other hand, is an interactive theorem prover used to verify  
mathematical specifications using its own input language Isabelle/Isar.  
Users specify inductive definitions and write proofs about them manually,  
albeit with the help of semi-automated tactics.

In this work, I have connected Isabelle as an underlying solver for Leon  
verification conditions. While Isabelle is much weaker in terms of  
automation, this has two advantages: Firstly, proofs in Isabelle, even  
those generated from automated tactics, have are justified against a  
minimal inference kernel. As opposed to ATPs, which are complex pieces of  
software, it is far less likely that a kernel-certified proof is unsound.  
Secondly, Isabelle's premier logic, HOL, has seen years of development of  
rich mathematical libraries. Proofs carried out in Isabelle have access to  
that, which means that there's a great potential for reuse of existing  
developments.
