Some new results are derived for complex n × n contractions and partial isometries, illustrating the natural way in which the EP concept enters the study of these matrices. It is shown that for any contraction K, 1 - K is EP and R(I - KK*)⊆R(I - K). where R(⋅) denotes the range of (⋅). It is further proven that if [image omitted] are n × n contractions with K1 and L1 of size k × k, then [image omitted] are also EP. |
