Wie kann ich aus verschiedenen vordefinierten Sätzen ein mathematisches Alphabet mit Klein- und Großbuchstaben konstruieren?

Ich verwende derzeit die RSFS-Buchstaben für Kaligraphiesymbole. Es gibt jedoch kein entsprechendes Kleinbuchstabenalphabet, daher habe ich begonnen, mit anderen zu experimentieren. Gibt es eine Möglichkeit, es so einzurichten, dass ich $\mathscr{Ker}$anstelle von schreiben kann $\mathscr{K}\mathcal{er}$, wie ich es bisher getan habe?

Antwort1

Hier ist eine Möglichkeit, dies basierend auf txfonts.stydem \varmathbbAlphabet zu tun. Da Sie keine Details angegeben haben, habe ich angenommen, dass das Kleinbuchstabenalphabet aus der Schriftart Chancery (Codename pzc) stammt. Natürlich passen die beiden überhaupt nicht zusammen, wie die schlechte Abstandseinstellung in Ker zeigt, also müssen Sie den Code an Ihre Bedürfnisse anpassen:

Ergebnis des Codes

\documentclass{article}

\DeclareSymbolFont{mathscrUC}{U}{rsfs}{m}{n}  % Formal Script for uppercase
\DeclareSymbolFont{mathscrLC}{OT1}{pzc}{m}{n} % Chancery for lowercase

Ein anderer Ansatz für das Problem: Erstelle eine virtuelle Schriftart aus den vorgegebenen Schriftarten und verwende sie anschließend als mathematisches Alphabet. Hier ist ein Einstieg zu virtuellen Schriftarten:Wie erstelle ich eine virtuelle Schriftart?
