Completeness of Boolean powers of Boolean algebras
Journal of the Mathematical Society of Japan, 1988 For complete Boolean algebras A and B, let A[B] denote the Boolean power of A by B. This paper investigates conditions under which A[B] is a complete Boolean algebra, using techniques of Boolean valued models. The link between this problem and Boolean valued models is provided by a result of \textit{R. M. Solovay} and \textit{S. Tennenbaum} [Ann. Math.,

Random Structures &Algorithms, Volume 68, Issue 3, May 2026.ABSTRACT Binary search trees (BSTs) are fundamental data structures whose performance is largely governed by tree height. We introduce a block model for constructing BSTs by embedding internal BSTs into the nodes of an external BST—a structure motivated by parallel data architectures—corresponding to composite permutations formed via Kronecker or ...

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 725-738, May 2026.We present a standardized and highly automated pipeline for megahertz X‐ray photon correlation spectroscopy (MHz‐XPCS) on soft‐matter samples at the MID instrument of the European XFEL. The workflow addresses AGIPD petabyte‐scale data handling, detector‐artifact correction, correlation analysis and FAIR data output, enabling routine MHz‐XPCS with ...

Cardinal invariants on Boolean algebras
, 2014 This book is concerned with cardinal number valued functions defined for any Boolean algebra. Examples of such functions are independence, which assigns to each Boolean algebra the supremum of the cardinalities of its free subalgebras, and cellularity ...

Pathways to gender‐transformative women's health aid: Comparative evidence from five donors
Development Policy Review, Volume 44, Issue 3, May 2026.Abstract Motivation Gender equality and women's health remain priorities, yet recent fiscal retrenchment and shifting geopolitical agendas have narrowed the space for gender‐transformative programming. Despite growing donor endorsement of gender‐transformative approaches, substantial gaps persist between rhetorical commitment and operational practice ...

Dense subtrees in complete Boolean algebras
, 2008 We characterize complete Boolean algebras with dense subtrees. The main results show that a complete Boolean algebra contains a dense tree if its generic filter collapses the algebra’s density to its distributivity number and the reverse holds for ...

Nearly projective Boolean algebras
, 1994 The book is a fairly complete and up-to-date survey of projectivity and its generalizations in the class of Boolean algebras. Although algebra adds its own methods and questions, many of the results presented were first proved by topologists in the more ...

Equational type characterization for sigma complete MV-algebras [PDF]
, 2013 In the framework of algebras with infinitary operations, an equational base for the category of σ-complete MV -algebras is given. In this way, we study some particular objects as simple algebras, directly irreducible algebras, injectives, etc.

On cohomology of locally profinite sets
Proceedings of the London Mathematical Society, Volume 132, Issue 5, May 2026.Abstract We construct a locally profinite set of cardinality ℵω$\aleph _{\omega }$ with infinitely many first cohomology classes of which any distinct finite product does not vanish. Building on this, we construct the first example of a nondescendable faithfully flat map between commutative rings of cardinality ℵω$\aleph _{\omega }$ within Zermelo ...
