I've occasionaly seen these arrows over numbers, but I don't know what they're called or exactly what they mean.
I'm assuming they have something to do with the motion, but I'm not sure.

Chevron above Arabic number marks pitch of the notes with respect to the root of the key. In this case these notes are 6 and 5 in scale of the key.
There is one flat in key signature, so the key could be F major or D minor. In this case it must be F major, as D is 6 in F (it is interval of major sixth above F), and C is 5 in F.
