Introduction
ICC: Implicit Computational Complexity
The problem: to design programming languages with bounded computational
complexity
The proposed solution: a ML-like approach
-calculus as paradigmatic programming language
Types as semantic properties of terms
Type assignment for -calculus such that:
types garantee the correctness of terms, in particular their complexity bound
if the type inference is decidable, the desired properties can be checked
statically at compilation time
The tecnical tool: the Light Logics (derived from the Linear Logic of Girard) where
the cut-elimination procedure is bounded in time by the size of the proof,
