On Different Definitions of Positive Definiteness
Mathematische Nachrichten, 1991Let the function \(T^*\) be defined by \(T^*(a)=T(a^{-1})^*\) for a function \(T\) of a group \(G\) into a Hilbert space. The authors show that the commutativity of \(G\) is equivalent to each of the conditions below: (1) \(T^*\) is positive definite for every representation \(T\) of \(G\) in Hilbert space.

On the definition of definition
Scientific and Technical Information Processing, 2010An attempt is undertaken to define the word "definition." The correlation of concepts, such as definition, term, discourse, and frame is discussed and a systematic definition of the term "definition" is given.

Alfonso Bedoya: Definitions, Definitions, and Definitions
2013Mathematics consists of definitions, equations, and proofs, and while the last two close the sale, definitions are like “Location, location, and location” in real estate. Types and pitfalls of definitions are discussed.

Ultimate-Definite and Symmetric-Definite Events and Automata
Journal of the ACM, 1965New classes of events and finite automata which generalize the noninitial definite class are introduced. These events, called “ultimate definite” (u.d.), “reverse u.d.” and “symmetric definite,” are investigated as to algebraic and closure properties. Effective decision procedures whereby it can be decided whether a given finite automata defines such ...

The limitations of clinical definitions of asthma which focus on the symptoms and signs of an acute attack of asthma are discussed. Implicit in such definitions is a research interest focused on the immediate causes of an attack. This is the final expression of a whole sequence of events and to fully understand the natural history of asthma requires ...

Definition of Definitions of Concepts
Social Forces, 1939A PPLIED sociology consists today more largely in the application of serviceable concepts and in tested techniques of social research, than in the application of laws or principles, which are few in verified number and usually too general in statement to solve some concrete problem.

RECENT scholarship within this journal (Baumgaertner and others 2016) found evidence of disputes between experts concerning the definition of suffering. I thought it might be useful – and simple – to remind readers of the definition of suffering. As Morton (2016) points out, ‘suffering’ is defined in the Animal …

Gore Vidal told a wonderful joke on the radio recently about the former British prime minister Harold Macmillan and a social visit he paid with his wife to the then French president, Charles de Gaulle. At the end of a long and probably very boring meal, Macmillan turned to Madame de Gaulle and asked politely what she was looking forward …
