Following Nazarathy and Shamir (1980), it is worth noting that the symbol Fz can be interpreted as an operator that applies on the function itself, keeping the original variables x and y, followed by a scaling that transform x and y into x/λz and y/λz. Although it may be of interest, the operator ap ...
