What does the following equation mean, as shown in the second to last line? What significance does this have in music? I have also seen this for different values as well.

@guidot - the magnified image is from halfway across the second last line– Elements In Space ♦Commented Aug 1, 2022 at 11:34

That magnified image was taken from the 2/4 bar below.– DresliCommented Aug 2, 2022 at 17:12

These metric equations sometimes accompany a time signature change. They indicate whether or not the note values (symbols) are to change duration.
When the symbols on either side of the metric equation are different, it usually means that the beat value (changing between un-dotted and dotted) is to remains the same duration, but the subdivisions of a beat has changed (between simple and compound).
In your case (the symbols on either side are the same) the note values should remain constant across the change in time signature, while the note value of a beat presumable does change.
