Essential Maps and Manifolds [PDF]
Proceedings of the American Mathematical Society, 1992 Let (M, partial derivative M) be a compact n-manifold with boundary, orientable over a field K with characteristic q . For f : (Y, partial derivative Y) --> (M, partial derivative M) , with Y compact, and (X, partial derivative X) a compact pair, g: X -->

Knowledge maps: An essential technique for conceptualisation [PDF]
Data & 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 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.

Multivalued essential maps of approximable and acyclic type
Applied Mathematics Letters, 2000 The authors consider multivalued approximable and multivalued acyclic maps. They prove that maps homotopic to an essential map in the class have the fixpoint property.

Essentiality for Mönch type maps [PDF]
Proceedings of the American Mathematical Society, 2000 A new fixed point theorem for Mönch maps on locally convex spaces is given. In addition, a continuation theorem for Mönch maps is presented.

Essential mappings and transfinite dimension [PDF]
Fundamenta Mathematicae, 1985 If \(\alpha\) is a countable ordinal, \(J^{\alpha}\) is \textit{D. W. Henderson}'s \(\alpha\)-dimensional absolute retract [ibid. 63, 167-173 (1968; Zbl 0167.513)] and Ind \(X\geq \alpha\), is there an essential \(f: X\to J^{\alpha}?\) The authors answer this question in the affirmative if \(\alpha =\omega\) and X is normal and in the negative if ...

A user-centered mapping design for geomorphological hazard thematic map
Journal of Maps, 2023 Numerous studies have concentrated on developing user-centered designs for hazard zone maps but rarely for hazard-oriented geomorphological maps, named as Geomorphological Hazard Thematic Maps (GHTMs) in this study, which provide more detailed ...
