 v30 ** Differential Forms / Tensor Fields** - tensor algebra computations for the case zero simplified: in order to make computations faster, an attribute _is_field is added (similar to scalar 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) - multiplication of tensor fields a with scalar fields f yields name f*a and latex name f \cdot a - coercion via restriction rearranged in scalar fields following tensor fields - minor code rearrangements, i.e. for code reuse or consistency - copies take the attribute _is_field from original in method copy (both for tensor fields and scalar fields) to ensure zero treatment - copy() now inherits the attribute _is_zero from the original (both for tensor fields and scalar fields) to ensure better zero treatment
