How do i express a chromatic polynomial as a falling factorial function? [attachment=0:szbeqan8]Capture.JPG[/attachment:szbeqan8] I understand the joinproduct, but it seems that in order to apply it I'd need to convert the chromatic polynomials into falling factorial functions like and and i dunno how to express that as a falling factorial edit: i think i kinda get it .... but i'm getting: and edit2: holy crap, it totally does = thanks everybody XD this is why i love this forum ... even when noone's responding it's still helpful XD my only question left is how do i do this without actually drawing out all the picture and using chromatic reduction?
