The first female mathematician to receive the prestigious Fields Medal is Maryam Mirzakhani from Stanford University. Mirzakhani said: "I will be happy if it encourages young female scientists and mathematicians. I am sure there will be many more women winning this kind of award in coming years." Mirzakhani was born and raised in Tehran, where as a young girl she dreamed of becoming a writer. By high school, however, her affinity for solving mathematical problems and working on proofs had shifted her sights.

The Kavli Week is celebrating the Kavli Prize with Ceremony Show, Popular science lectures, and academic symposia and lectures by the prize winners. A lot of money are involved, partly sponsored by the Fred Kavli Foundation.

Heidelberg Laureate Forum - Abel, Fields and Turing Laureates Meet the Next Generation. Winners of the prestigious Abel Prize, Fields Medal and Turing Award will meet ambitious young scientists starting with 23-27 September 2013.

The Abel Prize in mathematics (with value ~1Mil $) is given this year on 22 May 2012 to Endre Szemeredi, a Hungarian mathematician who worked, among other, in the fields of combinatorics and theoretical computer science.

Title: Towards Model Checking Contracts.
PDF fileSlides
Abstract: In this paper we present briefly our eforts towards model checking law contracts. Our approach uses the formal action-based specification language for contracts CL. The actions of the language are well studied and form a algebraic structure for actions found in contracts which are interpreted as guarded rooted trees. The algebra is proven complete with respect to the interpretation as guarded rooted trees. The purpose of the CL language in the model checking process is to restrict the specification of contracts such that to avoid many of the common mistakes and deontic paradoxes. CL is also used to write the properties that one wants to check on the contract. We use a translation of CL into mu-calculus in order to obtain the (extended) labeled transition system representing the model of the contract. This is given to the NuSMV tool as input. For now, NuSMV supports only LTL-like properties, so we cannot use our CL to specifiy the properties. The extension of NuSMV in this respect is left for future work. We have used this method on a real contract example between an Internet provider and a client.

Title: An Algebraic Structure for Actions found in Contracts.
PDF fileSlides
Abstract: We introduce in this paper an algebra of actions specially tailored to serve as basis of an action-based formalism for writing electronic contracts. The proposed algebra is based on the work on Kleene algebras but does not consider the Kleene star and introduces a new constructor for modelling concurrent actions. The algebraic structure is resource-aware and incorporates special actions called tests. In order to be in accordance with the intuition behind electronic contracts we consider new properties of the algebraic structure, in particular a conflict relation and a demanding partial order. We also study a canonical form of the actions which, among other things, helps to naturally define a notion of action negation. Our action negation is more general than just negation of atomic actions, but more restricted than the negation involving the universal relation. A standard interpretation of the algebra is given in terms of guarded rooted trees with specially defined operations on them. The algebra is proven to be complete over the standard interpretation.

Title: A Formal Language for Electronic Contracts.
PDF fileSlides
Abstract: In this paper we propose a formal language for writing electronic contracts, based on the deontic notions of obligation, permission, and prohibition. We take an ought-to-do approach, where deontic operators are applied to actions instead of state-of-affairs. We propose an extension of the mu-calculus in order to capture the intuitive meaning of the deontic notions and to express concurrent actions. We provide a translation of the contract language into the logic, the semantics of which faithfully captures the meaning of obligation, permission and prohibition. We also show how our language captures most of the intuitive desirable properties of electronic contracts, as well as how it avoids most of the classical paradoxes of deontic logic. We finally show its applicability on a contract example.

Title: Timed distributed pi-calculus.
PDF fileSlides
Abstract: We consider process algebras for modelling distributed systems with time constraints. For this task we must deal with access to resources, locations and interaction among processes. We extend the pi- calculus with locations, types and timers. Types are used to restrict the access to distributed resources. Timers define both timeouts for communication channels and timeouts for capabilities of the communication channels. We define the operational semantics by using a reduction relation. We introduce and study several timed barbed bisimulations.

Title: Modeling MolNet Systems with Timed Distributed pi-calculus.
PDF fileSlides
Abstract: In this work we first present a brief introduction to the new modeling framework Timed Distributed pi-calculus (TDpi). It is based on the pi-calculus and combines the resource access restrictions imposed by a typing system with time constraints and time coordination aspects. TDpi is intended to model distributed systems with time and resource constraints and coordination problems. The presentation focuses on the modeling of a MolNet system with the new calculus. MolNet is a tool for simulating behavior of molecular networks. It has a component based client-server architecture with a mathematical foundation on Dynamic Structure Discrete Event Systems formalism in order to simulate the continuous changes in a molecular network. A MolNet system is designed as a distributed system with a server coordinating communications between system components. Discussion about further work involves the verifier for models described in TDpi and its integration within the simulation tool.
