 v31 ** Differential Forms / Tensor Fields** - tensor algebra computations for the case zero simplified: in order to make computations faster, an attribute _is_zero is added (similar to scalar fields) - tensor algebra computations improved: - in order to make computations faster, an attribute _is_zero is added and checked (similar to scalar fields) - wedge product of differential forms with self leads to zero right away in case of odd order - multiplication of tensor fields a with scalar fields f yields name f*a and latex name f \cdot a
