Numerical Range of Two Operators in Semi-Inner Product Spaces by N. K. Sahu, C. Nahak, S. Nanda

“…In this paper, the numerical range for two operators (both linear and nonlinear) have been studied in semi-inner product spaces. The inclusion relations between numerical range, approximate point spectrum, compression spectrum, eigenspectrum, and spectrum have been established for two linear operators. …”
