Essential and inessential maps and continuation theorems

Applied Mathematics Letters, 2000
In the present paper the notion of essential map [\textit{A. Granas}, C. R. Acad. Sci. Paris, Sér. A 282, 983-985 (1976; Zbl 0348.47039)] is extended to a larger class of maps. For this new notion it is proved that if \(0\) is essential and \(0\cong F\), then \(F\) is essential.

Knowledge maps: An essential technique for conceptualisation [PDF]

Data and Knowledge Engineering, 2000
The process of conceptualisation is a fundamental problem-solving activity and, hence, is an essential activity for solving the problem of software systems construction. This paper first analyses the process of conceptualisation generally, that is, not as applied specifically to software systems, and establishes a general-purpose conceptualisation

Essential maps and coincidence principles for general classes of maps

Filomat, 2017
We introduce the notion of an essential map for a general class of maps. In addition we present homotopy and normalization type properties for these maps.

On essential spectra of operator-matrices and their Feshbach maps

Journal of Mathematical Analysis and Applications, 2004
A connection between the essential spectrum of certain operator-matrices and essential spectra of the corresponding “Feshbach maps” is discussed and applied to some concrete rational operator-valued ...
