A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

On places of algebraic function fields.

Journal für die reine und angewandte Mathematik (Crelles Journal), 1984
Let \(F\) be an algebraic function field in \(n\) variables over a field \(k\) of characteristic 0. Let \(Q\) be a place of \(F\), trivial on \(k\), with residue field \(FQ\) and value group \(v_Q(F)\). It is shown that that \(Q\) can be approximated by places \(P\) of \(F/k\) which have certain prescribed properties. For example, it is shown that, if \

Simple Algebras Over Rational Function Fields

Canadian Journal of Mathematics, 1979
The well-known Hasse-Brauer-Noether theorem states that a simple algebra with center a number field k splits over k (i.e., is a full matrix algebra) if and only if it splits over the completion of k at every rank one valuation of k. It is natural to ask whether this principle can be extended to a broader class of fields.

Kodaira Dimension of Algebraic Function Fields

American Journal of Mathematics, 1987
Es sei K ein algebraischer Funktionenkörper vom Transzendenzgrad d über einem beliebigen Konstantenkörper k. Besitzt K/k ein glattes eigentliches Modell X, so ist die Kodairadimension \(\kappa\) (X) von X unabhängig vom Modell, also durch K/k eindeutig bestimmt. Genauer gilt: Bezeichnet \(\omega_ X=\bigwedge^ d\Omega^ 1_{X/k}\) die kanonische Garbe auf
