Logic, Algebra and Truth Degrees 2025 (LATD 2025) will be held on 21-25 July 2025 at the University of Siena, Italy. It will be the ninth installment of a series that started as an official meeting of the working group on Mathematical Fuzzy Logic and has evolved into a wider meeting in Algebraic Logic and related areas. Its main goal is to foster collaboration between researchers in these areas, and to promote communication and cooperation with members of neighbouring fields.We invite contributions on any relevant aspects of logical systems (including many valued, fuzzy, substructural, modal and quantum logics), in particular:* Proof theory and computational complexity* Algebraic semantics and abstract algebraic logic* First-order, higher-order and modal formalisms* Geometric and game-theoretic aspects* Applications and foundational issues
