Linear transformation from endormorphism to real number

39 Views Asked by At

For a finite dimensional vector space $V$, is there a linear transformation between its endomorphism and real number, please? I suspect that since the element of the endomorphism can be represented by a square matrix given a basis, then the question becomes to find a liner transformation from a set of matrix to real number. One such thing I can think of is determinant. Is this guess true, please?

the determinant is not exactly linear, it is is multilinear. It is simpler to take just the first coordinate of your matrix.
