Weakest Congruences, Fairness and Compositional Process-Algebraic Verification
Tampereen teknillinen yliopisto, Julkaisuja (Tampere University of Technology, 2004)
ArtikkeliväitöskirjaTraditionally, computer programs have been thought of as entities which take some input, execute a sequence of statements that process this input, and then return the result. More recently, concurrent and reactive computer ... -
Weakly elliptic damping gives sharp decay
(13.10.2025)
articleWe prove that weakly elliptic damping gives sharp energy decay for the abstract damped wave semigroup, where the damping is not in the functional calculus. In this case, there is no overdamping. We show applications in ... -
Weakly Supervised Learning for Quark vs Gluon Jet Discrimination
