Ticket #28916 – Description
v9 v10 1 1 This makes the coercion model of mixed forms more robust against modifications regarding differential forms. For instance: As soon as all differential forms of another mixed form have a coerce map, the mixed form has one too. The same now holds for any algebraic element which is coercible into a single differential form. 2 2 3 At this stage, the method `degree` is used and special cases are handled separately. But notice that not all coercible objects provide this method (symbol dring). Or conversely, having this method doesn't mean being coercible into a differential form. Hence this invocation is now entirely avoided.3 At this stage, the method `degree` is used and special cases are handled separately.
