 Infinite-dimensional vector function

An infinite-dimensional vector function refers to a function whose range or domain consists of infinite-dimensional vector spaces. In simpler terms, it is a function that maps elements from one space (often a space of scalars or finite-dimensional vectors) to a space that has infinitely many degrees of freedom. ### Key Concepts: 1. **Vector Spaces**: - A vector space is a collection of vectors that can be added together and multiplied by scalars.
