Second degree semi-classical forms of class \(s=1\). The symmetric case
The aim of this paper is to determine all the symmetric semi-classical forms of class \(s=1\), which are also of second degree. Only some forms, introduced by Chihara, which satisfy a certain condition, possess this property. The author shows that there exists a relation between these forms and second degree classical forms.
