Weak Galois and Weak Cocleft Coextensions
Algebra Colloquium, 2007For a weak entwining structure (A, C, ψ) living in a braided monoidal category with equalizers and coequalizers, we formulate the notion of weak A-Galois coextension with normal basis and we show that these Galois coextensions are equivalent to the weak A-cocleft coextensions introduced by the authors.

WEAK INJECTIVE AND WEAK FLAT COMPLEXES
Glasgow Mathematical Journal, 2015AbstractLet R be an arbitrary ring. We introduce and study a generalization of injective and flat complexes of modules, called weak injective and weak flat complexes of modules respectively. We show that a complex C is weak injective (resp. weak flat) if and only if C is exact and all cycles of C are weak injective (resp. weak flat) as R-modules.

Weak Reflections and Weak Factorization Systems
Applied Categorical Structures, 2008It is known that in nice categories, saturated factorization systems are equivalent to reflective subcategories, that is, there is an adjunction between them inducing a bijection [\textit{C. Cassidy, M. Hébert} and \textit{G. M. Kelly}, J. Aust. Math. Soc., Ser. A 38, 287--329 (1985; Zbl 0573.18002) and ibid. 41, 286 (1986; Zbl 0601.18001)]. This paper

AbstractThis chapter outlines a new approach to the investigation of aphasics' linguistic errors. The model represents a further development of ideas outlined in Avrutin (1999). It shows that damage to Broca's region diminishes the amount of resources necessary for conducting operations involving narrow syntax.
