2016-08-24 2016 Endlich-dimensionale Nichols-Algebren von Diagonalem Typ über Körpern von positiver Charakteristik In dieser Arbeit gelingt es uns, die endlich dimensionalen Nichols-Algebren von diagonalem Typ über Körpern von positiver Charakteristik zu klassifizieren. Das vollständige Ergebnis kann durch Induktion über den Rang von Nichols-Algebren gegeben werden.
