Higher-rank numerical ranges are a generalization of the classical numerical range, which has been extensively studied in linear algebra and operator theory. This talk will introduce the concept of higher-rank numerical ranges and explore their properties from the perspective of real algebraic geometry. To illustrate the key concepts, I will present three concrete examples that showcase the diverse behavior and rich structure of higher-rank numerical ranges.
