Notions of amalgamation for AECs and categoricity [PDF]

open access: yesarXiv, 2021
Motivated by the free products of groups, the direct sums of modules, and Shelah's $(\lambda,2)$-goodness, we study strong amalgamation properties in Abstract Elementary Classes. Such a notion of amalgamation consists of a selection of certain amalgams for every triple $M_0\leq M_1, M_2$, and we show that if $K$ designates a unique strong amalgam to ...

Exactness of reduced amalgamated free product C*-algebras [PDF]

open access: yesarXiv, 1999
Some completely positive maps on reduced amalgamated free products of C*-algebras are constructed; these allow a proof that the class of exact unital C*-algebras is closed under taking reduced amalgamated free products. Consequently, the class of exact discrete groups is closed under taking amalgamated free products.

Positive Strong Amalgamation [PDF]

open access: yesarXiv, 2019
We present the notions of positively complete theory and general forms of amalgamation in the framework of positive logic. We explore the fundamental properties of positively complete theories and study the behaviour of companion theories by a change of constants in the language.

Light‐Driven PAA Adhesive: A Green Bonding Platform Integrating High‐Performance, Environmental Resilience, and Closed‐Loop Recyclability

open access: yesAdvanced Science, EarlyView.
This investigation introduces the formulation of a cutting‐edge, robust polyacrylic aqueous adhesive (PAA), synthesized through the employment of visible‐light initiated polymerization. The adhesive demonstrates minimal energy demand, environmental friendliness, robust adhesive properties (20.86 MPa on wood), remarkable thermal stability (with ...

Positive Amalgamation [PDF]

open access: yesarXiv, 2012
We study the amalgamation property in positive logic. We give some connections between the amalgamation property and Robinson theories, model-complete theories and the Hausdorff property.
