Finitary semantics of linear logic and higher-order model-checking
[article]
2015
arXiv

The main idea is to start from an infinitary and colored relational semantics of the lambdaY-calculus already formulated, and to replace it by its finitary counterpart based on finite prime-algebraic lattices ...
In this paper, we explain how the connection between higher-order model-checking and linear logic recently exhibited by the authors leads to a new and conceptually enlightening proof of the selection problem ...
Future work includes a detailed comparison with a similar line of work on finite models of the λ Y -calculus currently developed by Salvati and Walukiewicz [10] . ...

Correctness of this encoding reduces decidability of the open HoRS equivalence problem -- and, thus, the LambdaY-calculus B\"ohm tree equivalence problem -- to semi-decidability of coinductive HoCHC over ...
Thus, s is an upper bound on D. However, D is the least upper bound on this set, so D ⊑ s. ...
Although HoRS are programs of a simply-typed λ Y-calculus, constructed from uninterpreted function symbols, they define a strict subsystem of the λ Y-calculus: the same set of trees as ground-type λ Y-terms ...

We investigate the existence of solutions for an increasing variables singular m-dimensional system of fractional q-differential equations on a time scale. ...
In this singular system, the first equation has two variables and the number of variables increases permanently. ...

The seminar focussed on complexity and algorithmic issues for the verification of infinite-state systems, with special emphasis on reachability problems. ...
If zero-tests are allowed-one speaks of "Minsky machines"-, counter systems have the power of Turing machines, and so all their verification problems ...
LambdaY-calculus is simply typed lambda calculus with fixpoint operators. This calculus faithfully models control in higher-order programs. ...
