Operations and compositions in transrecursive operators

Cybernetics and Systems Analysis, 1994
Earlier, the authors introduced classes of alphabetic operators that have greater computational possibilities than classical algorithms. In Dokl. Akad. Nauk SSSR 321, No. 5, 876-879 (1991), they gave a uniform procedure for obtaining such alphabetic operators, which will be called transrecursive operators in what follows.

Multiple-Attribute Group Decision-Making Based on q-Rung Orthopair Fuzzy Power Maclaurin Symmetric Mean Operators

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2020
To be able to describe more complex fuzzy uncertainty information effectively, the concept of ${q}$ -rung orthopair fuzzy sets ( ${q}$ -ROFSs) was first proposed by Yager.

On operator algebras and operator ranges [PDF]

Integral Equations and Operator Theory, 1986
Some further results are given and some questions raised concerning operator algebras of countable range multiplicity. An example is given of an abelian range cyclic algebra that does not have finite strict multiplicity. On the other hand it is shown that every uniformly closed abelian range cyclic algebra is strictly cyclic.

Operations and Operatives

2014
Operation RUVANDIZ-SCHLUCHT (ROWANDUZ GORGE) is said to have been a detailed scheme originally submitted to Hans-Otto Wagner of Abwehr II in 1941 by Paul Leverkuehn of KONO in Istanbul for a 2–3-man parachute team to carry out the demolition of bridges on the 185 km-long, strategic asphalt road, known even today as the Hamilton Road, constructed by the

Multiple-Attribute Decision-Making Based on Archimedean Bonferroni Operators of q-Rung Orthopair Fuzzy Numbers

IEEE transactions on fuzzy systems, 2019
The theory of $q$-rung orthopair fuzzy sets ($q$-ROFSs) proposed by Yager effectively describes fuzzy information in the real world. Because $q$-ROFSs contain the parameter $q$ and can adjust the range of expressed fuzzy information, they are superior to

Pituitary Incidentaloma: to Operate or Not to Operate ?

Acta Chirurgica Belgica, 2012
The wide use of sophisticated imaging techniques has led to the discovery of asymptomatic pituitary lesions, which are called 'incidentalomas'. Their global prevalence averages 10% whereas that of macroadenomas (> 10 mm) is less than 1%. The most frequently encountered lesions are non-functioning adenomas followed by Rathke's cleft cysts.

Commutators of operators

American Journal of Mathematics, 1952
A mathematical formulation of the famous Heisenberg uncertainty principle is that a certain pair of linear transformations P and Q satisfies, after suitable normalizations, the equation PQ - QP = 1. It is easy enough to produce a concrete example of this behavior; consider L2(-∞, +∞) and let P and Q be the differentiation transformation and the ...

Operations on Closure Operators

1995
Despite the powerful continuity condition, the notion of closure operator is very general. It is therefore important to provide tools for improving a given operator. Fortunately, there is a natural lattice structure for closure operators that allows us to distinguish between properties stable under meet (idempotency, hereditariness, productivity), and ...

ON REDUCTIVE OPERATORS AND OPERATOR ALGEBRAS

Mathematics of the USSR-Izvestiya, 1976
We prove a theorem on the structure of weakly closed reductive operator algebras. The proof essentially relies on a known result of V. I. Lomonosov on transitive operator algebras containing a nonzero compact operator. We deduce a number of corollaries which apply to the reductivity problem.Bibliography: 20 titles.
