A representation of \(\text{Spin}(4)\) on the eigenspinors of the Dirac operator on \(S^3\). (English) Zbl 0979.58012

The author constructs the eigenspinors of the Dirac operator \(D_3\) on the sphere \(S^3\) from a representation theoretical point of view. The corresponding eigenspaces give a highest weight representation of Spin(4). The eigenspinors are represented by using the matrix components of the irreducible representation of \(SU(2)\) and the actions of Spin(4) and \(D_3\) on the eigenspinors are calculated explicitly. It is possible to extend the results to zero mode spinors in \(D_4\) on \(S^4\).
