Diese Arbeit beschäftigt sich mit dispersiven Abschätzungen für eine Klasse radialsymmetrischer eindimensionaler Schrödingeroperatoren, definiert auf der positiven Halbachse, welche zahlreiche Anwendungen in der mathematischen Physik besitzen. Wir verallgemeinern einige bereits existierende Resultate und beschäftigen uns mit einigen bisher noch nicht behandelten Grenzfällen: Im ersten Teil betrachten wir den Fall beliebiger Randbedingungen; der zweite Artikel behandelt einen kritischen Fall, welcher bis jetzt noch nicht im Detail analysiert wurde, da er in einigen technischen Details um einiges anspruchsvoller ist; im dritten Teil beschäftigen wir uns mit einigen Eigenschaften der dazugehörigen Transformationsoperatoren, wobei der Fokus dar...
