Definitely Life but not Definitively
Origins of Life and Evolution of Biospheres, 2006Although there have been attempts at a definition of life from many disciplines, none is accepted by all as definitive. Some people believe that it is impossible to define 'life' adequately at the moment. We agree with this point of view on linguistic grounds, examining the different types of definition, the contexts in which they are used and their ...

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 ...

Chest, 1987
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 ...
