  • Ticket #28159 – Description

    v54 v121  
    1313
    1414- restriction of vectorframes depended on some strange order: fixed!
    15 - `SR` enforcement for automorphism field inversion removed (due to ticket #28189)
    16 - `is_unit()` method implemented for scalar fields (to check whether a matrix with entries in the scalar field algebra is invertible)
     15- ~~`SR` enforcement for automorphism field inversion removed (due to ticket #28189)~~
     16- `is_unit()` method superficially implemented for scalar fields to ensure division free matrix inversion for changes of frames (may be removed when #28629 is solved)
    1717
    1818**Planned in the farther future**
    1919
    20 - sections of general tensor products
     20- sections of general tensor products and automorphism fields on vector bundles
    2121- tensor products and Whitney sums of vector bundles
    22 - return the total space with charts
     22- better zero treatment as in #28562
     23- `TensorField` inherits from `Section`, `VectorFrame` inherits from `LocalFrame`
     24- total space comes with induced charts
