Free bounded archimedean $$\ell $$-algebras [PDF]
Applied Categorical Structures, 2021 We show that free objects on sets do not exist in the category $bal$ of bounded archimedean $\ell$-algebras. On the other hand, we introduce the category of weighted sets and prove that free objects on weighted sets do exist in $bal$. We conclude by discussing several consequences of this result.

Free algebra structure: categorical algebras [PDF]
Bulletin of the Australian Mathematical Society, 1970 One of the more important concepts in the study of universal algebras is that of a free algebra. It is our purpose in this communication to describe the structure of the free algebra Kk() of k generators (k a positive integer) determined by a categorical algebra, and to indicate how this information encompasses results in such diverse areas as the ...

Acting Semicircular Elements Induced by Orthogonal Projections on Von-Neumann-Algebras
Mathematics, 2017 In this paper, we construct a free semicircular family induced by Z -many mutually-orthogonal projections, and construct Banach ∗-probability spaces ...

Certain Bounds of Formulas in Free Temporal Algebras
Axioms, 2023 In this paper, we give a basic structure theorem based on the study of extreme cases for the value of ≺ (the classical precedence relation between ultrafilters), i.e., ≺=∅ and no isolated element in ≺.

Towards free localic algebras [PDF]
Categories and General Algebraic Structures with ApplicationsThe purpose of this paper is to establish that the underlying objectfunctor from the models of a Lawvere theory to the base category creates limitsand coequalisers of all parallel pairs of homomorphisms whose underlying pairadmit a split coequaliser.

General Ramified Recurrence is Sound for Polynomial Time [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 Leivant's ramified recurrence is one of the earliest examples of an implicit characterization of the polytime functions as a subalgebra of the primitive recursive functions.

Journal of High Energy Physics, 2019 We construct free Lie algebras which, together with the algebra of spatial rotations, form infinite-dimensional extensions of finite-dimensional Galilei Maxwell algebras appearing as global spacetime symmetries of extended non-relativistic objects and ...

Decoherence-free algebra [PDF]
Physics Letters A, 2003 We consider the decoherence free subalgebra which satisfies the minimal condition introduced by Alicki. We show the manifest form of it and relate the subalgebra with the Kraus representation. The arguments also provides a new proof for generalized L ders theorem.

Correspondences among CFTs with different W-algebra symmetry
Nuclear Physics B, 2020 W-algebras are constructed via quantum Hamiltonian reduction associated with a Lie algebra g and an sl(2)-embedding into g. We derive correspondences among correlation functions of theories having different W-algebras as symmetry algebras.
