The distance formula ‖ T t-λ I) −1 ‖= [Dist (λ, σ ( T )] −1, λ∉σ ( T ), for hyponormal operators, is generalized to p -hyponormal operators for 0< p <1. Several other results involving eigenspaces of U and T , the joint point spectrum, and the spectral radius are also otained, where T = ( T * T) 1/2 and U is the ...

In mathematics, an operator is generally a mapping or function that acts on elements of a space to produce elements of another space (possibly and sometimes required to be the same space). There is no general definition of an operator, but the …
