On the Spreadsheet Presentation of Proof Obligations
"... . A compact and structured format for presenting proof obligations is described. The format places the formulas and proof obligations in the form of a spreadsheet, where rows are formulas, columns are obligations, and cells record whether and how a formula appears in an obligation. This spreadsheet ..."

Proof Obligations for Monomorphicity
, 1995
"... In certain applications of formal methods to development of correct software one wants the requirement specification to be monomorphic, i.e. that every two termgenerated models of it are isomorphic. Consequently, the question arises how to guarantee monomorphicity (which is not decidable in general ..."

Architectural Specifications, Proof Obligations, and Decomposition
, 1997
"... Architectural specifications can express correctness requirements of concurrent systems at a high level without any reference to component functionality. Then proof obligations derived from such specifications can be discharged as model checking tasks in a suitable behavioral model where components ..."

Configurable Proof Obligations in the Frog Toolkit
 IN PROC. FIFTH IEEE INTERNATIONAL CONFERENCE ON SOFTWARE ENGINEERING AND FORMAL METHODS, IEEE COMPUTER
, 2007
"... In model based formal methods, incompatible tools for different techniques is the norm. However, greater applicability to industrial scale systems increasingly requires combining the strengths of different techniques, in line with the Verification Grand Challenge. The Frog tool embodies a construct ..."

based specification syntax, and its metalanguage FrogCCL allows the generic configuration of both a construct’s syntax and its proof obligations. For a specific system, Frog generates the system’s verification conditions mechanically from the generic ones. Relationships between systems such as refinement
Proof Obligations for RealTime Refinement
 In 6th Refinement Workshop, edited by D. Till, BCS
, 1993
"... Existing "algorithm design" rules, for refining Z specifications to structured highlevel language code, are extended with proof obligations that preserve specified realtime, as well as functional, behaviour. 1 Introduction Existing refinement methods provide a means of developing progra ..."

A Proof Obligation Generator for VDMSL
 In FME'97, LNCS 1313
, 1997
"... . In this paper an extension of the IFAD VDMSL Toolbox with a proof obligation generator is described. Static type checking in VDM is undecidable in general and therefore the type checker must be incomplete. Hence, for the "difficult" parts introducing undecidability, it is up to the user ..."

Minimal Proof Obligations for Ordered Sets
"... We show how the smallest set of lemmas can be generated that is sufficient to prove an assumed partialorder relation on a finite set. This idea is developed from a mathematical formulation up to an algorithm implemented in ML. The process of establishing a Hasse diagram from a set of subsets serves ..."

We show how the smallest set of lemmas can be generated that is sufficient to prove an assumed partialorder relation on a finite set. This idea is developed from a mathematical formulation up to an algorithm implemented in ML. The process of establishing a Hasse diagram from a set of subsets serves as an applicative example.
