On pg. 60 of Nolting Theoretical Physics 1 for the definition of a vector multiplied by a scalar the book shows two little up arrows if the scalar is greater than zero and an little up arrow and then a little down arrow if the scalar is less than zero. Then again on pg. 61 for definition 1.139 there are two little up arrows (similar to particle spin notation) in between the unit vector and the vector.
What do these little pairs of arrows mean? I have never seen this notation for vectors before. Could someone please explain their semantics?
