Generalized Casimir Operators

Canadian Journal of Mathematics, 1969
Throughout this paper, S will be a ring (not necessarily commutative) with an identity element ls ≠ 0s. We shall use R to denote a second ring, and ϕ: S→ R will be a fixed ring homomorphism for which ϕ1S = 1R.In (7), Higman generalized the Casimir operator of classical theory and used his generalization to characterize relatively projective and ...

Underexcited Operations of Generators

IEEE Transactions on Power Apparatus and Systems, 1963
This paper discusses two methods for controlling line-charging kilovars (kvar) and voltages on a lightly loaded 345-kv system. One method utilizes shunt reactors, while the other takes advantage of underexcited capabilities of modern turbine generators utilizing appropriate control.

Complex Interval-valued Intuitionistic Fuzzy Sets and their Aggregation Operators

Fundamenta Informaticae, 2019
The objective of this manuscript is to present the concept of the complex interval-valued intuitionistic fuzzy (CIVIF) set, their algebraic operations and their corresponding aggregation operators, which can better represent the time-periodic problems ...

Unbounded Linear Operators

Oxford Scholarship Online, 2018
This chapter is concerned with closable and closed operators in Hilbert spaces, especially with the special classes of symmetric, J-symmetric, accretive and sectorial operators. The Stone–von Neumann theory of extensions of symmetric operators is treated

A Generalized Averaging Operator

Canadian Journal of Mathematics, 1956
1. Introduction. The averaging operator has an extensive literature, the most detailed account being that of Nörlund(4). In discussing solutions of the functional relation1.1he defines a “principal solution” (4, p. 41) by means of a summability process, and later, working in terms of complex numbers, he obtains (4, p. 70) a principal solution of (1.1)

Turbine operation, general characteristics

2010
If the system head imposed on the pump exceeds the shut-off head, liquid flows back through the pump from the discharge to the suction nozzle in the “pumping-brake mode”. There are a number of other abnormal modes of operation which are described by the “general characteristics”.

Generalized Operator Riccati Equations

SIAM Journal on Mathematical Analysis, 1985
Summary: The Riccati equation \(dU/dt=AU+UB^*+UCU+D\) on the space \({\mathcal L}(X)\) of bounded linear operators on a reflexive Banach space X arises in control theory and transport theory. A more general problem is the following. Let A and B be closed linear operators in X and \(X^*\) respectively and let \({\mathcal F}\) be a map from [0,T)\(\times

On Generalized Averaging Operators

Canadian Journal of Mathematics, 1958
Let Sumner (4) has discussed for arbitrary real λ and h, whereƒ(Z) is an entire function of exponential type I shall show that in this case an alternative definition of ∇λλ, which leads to Sumner's results more quickly, is equivalent to Sumner's. (However, Sumner's definition is, in principle, applicable to a wider class of functions.)
