Sage output is correct: it says that `KA`

is a *2-vector* field, not that it is a *vector* field. A 2-vector field is a tensor field of type (0,2), as you can check:

```
sage: KA.tensor_type()
(2, 0)
```

You can also take a look at `KA`

(`/\`

stands for the wedge product):

```
sage: KA.display()
-3/2 d/dx/\d/dy - 3 d/dx/\d/dz - 3/2 d/dy/\d/dz
```

See the multivector field documentation for more details about 2-vector vields.

Sage output is correct: it says that `KA`

is a *2-vector* field, not that it is a *vector* field. A 2-vector field is a tensor field of type ~~(0,2), ~~(2,0), as you can check:

```
sage: KA.tensor_type()
(2, 0)
```

You can also take a look at `KA`

(`/\`

stands for the wedge product):

```
sage: KA.display()
-3/2 d/dx/\d/dy - 3 d/dx/\d/dz - 3/2 d/dy/\d/dz
```
