A multilinear map is a function that is linear in each of its arguments, meaning that if all but one argument is held constant, the map behaves as a linear transformation with respect to the remaining variable. These maps are fundamental in the study of tensor products and are crucial in fields like differential geometry, algebra, and functional analysis.

A linear transformation is a function between vector spaces that preserves vector addition and scalar multiplication, mapping lines to lines or points through the origin. These transformations can be represented by matrices, making them fundamental in solving systems of linear equations and understanding geometric transformations in higher dimensions.

Tensor products are a mathematical construction that allow for the combination of vector spaces, facilitating the representation of multilinear relationships. They are crucial in fields such as quantum mechanics, where they enable the description of composite systems by combining state spaces of individual components.
