Is divergence a linear operator

WebDec 8, 2024 · There are two special functions of operators that play a key role in the theory of linear vector spaces. They are the trace and the determinant of an operator, denoted by Tr ( A) and det ( A), respectively. While the trace and determinant are most conveniently evaluated in matrix representation, they are independent of the chosen basis. WebHere bilinear operator and the divergence-free vector field V: ℝ 4 ↦ ℝ 4 defined by the equalities (6.14) Proof.
