What is the meaning of det V and det V* in Generalised Complex geometry?

In summary, a determinant of a vector space is a mathematical tool that calculates the properties of a vector space, such as its size, shape, and orientation. It is typically calculated using the cross product or dot product of the vectors in the space, as well as the matrix representation of the vectors. The determinant provides information about linear independence and the volume of the parallelepiped spanned by the vectors. It is important in various areas of mathematics and is closely related to concepts such as eigenvalues, eigenvectors, and determinants of matrices. It also has connections to topics such as linear independence, rank, and invertibility of matrices.

Hi, I'm a reading a thesis on Generalised Complex geometry and it mentions an object " det V" and "det V*", for a real vector space V, and its dual V*. Could anyone tell me what this notation means? I've been unable to find anything mentioning a determinant of an entire vector space, so I'm fairly confused! The thesis I'm reading is http://arxiv.org/abs/math/0401221v1, and the det V first appears on page 11.
Thanks!

If V is n-dimensional, it probably means the repeated wedge product [itex]\wedge^n V[/itex].
