Hallo zusammen,
leider habe ich ein Problem mit dem Absatz: In dem geschriebenen Text wird an sehr ungünstigen stellen eine neue Zeile angefangen, was in diesem Zusammenhang leider überhaupt nicht geht.
Ich habe schon \begin{sloppypar} versucht, was eigentlich auch gut geht, jedoch leider die Paragraphüberschrift darunter, was ich auch nicht möchte.
Ich gebe euch hierzu mal ein Beispiel und hoffe, dass mir jemand hierzu helfen kann.
