Quantum Error Correction and Generalized Numerical Ranges

The numerical range is a useful tool for studying matrices and operators, and there are many generalizations of the concept motivated by theory and applications. In this talk, we focus on the higher rank numerical range, which arises from the study of quantum error correction. Recent results and open problems on the topic will be described.
