(generalized) backward difference operator

(suggested new terminology) I suggest ‘f(x) – f(red(x)’ as the (generalized) backward difference operator, where ‘red’ is short for ‘reduction of’. (This is a ‘horizontal’ generalization, as opposed to a ‘vertical’ generalization as might be needed in heavy-duty numerical analysis.) Two common forms of reduction of x are -x and x – 1. Actual use … Continue reading (generalized) backward difference operator
