Theorem ldepslinc 42623
Description: For (left) vector spaces, isldepslvec2 42599 provides an alternative definition of being a linearly dependent subset, whereas ldepsnlinc 42622 indicates that there is not an analogous alternative definition for arbitrary (left) modules. (Contributed by AV, 25-May-2019.) (Revised by AV, 30-Jul-2019.)
