WebMay 1, 2024 · Anderson's theorem states that if the numerical range W (A) of an n-by-n matrix A is contained in the unit disk D ‾ and intersects with the unit circle at more than n points, then W (A) = D ‾.An analogue of this result for compact A in an infinite dimensional setting was established by Gau and Wu. We consider here the case of A being the sum of …
