Summary
The conjecture that any linear group representation on a real space which is transitive on the unit sphere possesses also gradient property is proved.
Riassunto
Si dimostra la congettura secondo cui ogni rappresentazione lineare di un gruppo che sia transitiva sulla sfera gode della proprietà gradiente.
Резюме
Доказывается предположение, что линейное групповое представление на вещественном пространстве, которое является транзитивным на единичной сфере, также обладает градиентным свойством.
