Abstract. When defined with general elimination/application rules, natural deduction and λ-calculus become closer to sequent calculus. In order to get real isomorphism, normalisa...
We introduce explicit fusions of names. To `fuse' two names is to declare that they may be used interchangeably. An explicit fusion is one that can exist in parallel with som...
The Dependency Core Calculus (DCC) is an extension of the computational lambda calculus that was designed in order to capture the notion of dependency that arises in information-f...
In this paper we prove that the derivability problems for productfree Lambek calculus and product-free Lambek calculus allowing empty premises are NP-complete. Also we introduce a...
Abstract We prove that Polynomial Calculus and Polynomial Calculus with Resolution are not automatizable, unless W[P]-hard problems are fixed parameter tractable by one-side error...
