ThisRepeated Eigenvalues Repeated Eignevalues Again, we start with the real 2 × 2 system . = Ax. We say an eigenvalue λ1 of A is repeated if it is a multiple root of the char acteristic equation of A; in our case, as this is a quadratic equation, the only possible case is when λ1 is a double real root. Proof: For each eigenvalue, choose an orthonormal basis for its eigenspace. For 1, choose the basis so that it includes v 1.
