This is the page of a small reading and talking group involving [[people|People]] working on/with model checking techniques, all members of the [[FATA|http://dcs.gla.ac.uk/research/index.cfm?resgroup=FATA]] research group, in the [[Department of Computing Science|http://dcs.gla.ac.uk]]. The meetings consists of informal talks and writing on the whiteboard. 

''Time'': (usually) on every Wednesday at 2 p.m.
''Place'': (usually) in [[Muffy|http://dcs.gla.ac.uk/~muffy]]'s office, S171 or in SAWB 404

Next meeting: to be announced.
For comments, remarks, questions or details, please feel free to contact the responsible of the model checkers' meetings, [[Oana-Maria Andrei|http://dcs.gla.ac.uk/~oandrei]].

* Wednesay 29: ''Muffy'' on //term rewriting, confluence and Knuth Bendix completion//

* December 1 at 3 p.m.: ''Andrea'' on //bisimulation using fixpoint theory//
* December 8 at 3 p.m.: ''Oana'' on //runtime verification//

* December 8th at 2pm: ''Andrea'' on //epsilon-bisimulation//
* December 1st at 2pm: [[Iain McGinniss|http://www.iainmcgin.co.uk/]]  on //Modular Verification of Typestate Modelled Objects//

Abstract: 
------------
Object oriented languages have nice properties that make modular verification feasible. An object in languages such as Java and C# offers a fixed, well defined interface, and its implementation uses the defined interfaces of other objects to implement its functionality. This cleanly splits verification into two tasks, corresponding to the two sides of the "code contract": verification of a client of an interface, and verification of an implementation of an interface.

When using "typestate", making interfaces stateful and therefore making context important in performing verification, model checking becomes an important tool. The state space of an object is the superposition of the state of all its fields, while the path through the state space is determined by the type checker. In this talk I hope to discuss and find practical solutions for the integration of model checking and type checking to create an efficient, modular verification tool.
