Some meetings were private and informal. For these reasons, they are not recorded here.

- **"Logic and Categories"** (March 24th, 2023) by Tito and Valentin Maestracci. Chair: Pablo Donato.
	+ ["Pourquoi les catégories sont la bonne façon de faire de la sémantique dénotationnelle"](https://nguyentito.eu/2023-03-refl.pdf), Tito (1h)
	+ "Catégories monoïdales à trace", Valentin Maestracci (1h)
- **"ReFL first seminar of the year"** (February 21, 2023) by Pablo Donato, Davide Barbarossa, Adrien Ragot, Boris Eng, Sidney Congard (around 13 people online). Chair: Boris Eng.
	+ "Du calcul des séquents à la logique linéaire", Pablo Donato (30min)
	+ "Correspondance de Curry-Howard et théorie des types", Davide Barbarossa (30min)
	+ "Réseaux de preuve multiplicatifs avec règle daemon", Adrien Ragot (30min)
	+ ["Introduction à la géométrie de l'interaction originale de Girard"](/documents/slides_tc1_2023.pdf), Boris Eng (30min)
	+ "Introduction à la syntaxe transcendantale", Sidney Congard (30min)
- **"Freedom and Control in Logic and Computation"** (February 1st, 2023) (4 people).
	+ Apodictic and Epidictic in Girard's transcendental syntax. Control over computation (synchronicity, sequentiality, direction of computation).
- **"Proof-nets and Deep Inference"** (April 27, 2022) by Pablo Donato (5 people).
	+ Comparison between deep inference and proof-nets. Non-sequentialisable multiplicative connectives, ludics, proof assistants, sequent calculi as recipes for computational objects (constellations).
- **"Computation and Meaning"** (March 23, 2022) by Boris Eng (8 people).
	+ Discussion on stellar resolution and ways to put meaning on it (Girard's "usine" and "usage"), correctness criterion, realisability theory.
- **"Lambda-calculus and stellar resolution"** (March 9, 2022) by Boris Eng and Julien Marquet (6 people).
	+ Discussion on possible encodings of lambda-calculus and Lafont's interaction nets with unification (by using stellar resolution). Decomposition of tests as constellations. Discussions on optimal reduction of lambda-calculus.
- **Round table discussion at CIRM's "Logic and Interaction"** thematic month (February 2022) (8 people).
	+ Discussions on Girard's transcendental syntax. Focus on Girard's "conceptual knitting".
