Lecture
Linear Algebra: Bijections and Cardinality
Description
This lecture covers the concept of bijections in linear algebra, explaining how a map from one set to another can be a bijection if it is both injective and surjective. It also delves into the notion of cardinality, discussing how two sets have the same cardinality if there exists a bijection between them. The instructor illustrates these concepts with examples and emphasizes the importance of understanding the unique image and elements in the context of injective functions.
