?? does concept of "kaehler differential" (??? ...) live at toric level ???? .... ????

???maybe no ??? "derivation" ... ??? "leibniz" ... ???? ....

hmmm.... ??? .....

a*b = c

d = 1 ... ??? ....

???? but .... ????? ideal power filtration of diagonal ...... ????? .....

??? hmmm .... ?? but .... any good cocone interpretation here ??? .... ??? ....

?? hmmm .... "toric ideal" ..... ????? ....... ???? hmmm, as hidden ???? .... ?????

a = o .... vs b = c .... ????? b/c = 1 ..... ????? ....... ?????? .....

??? the ideals for which there's a nice pictorial "toric" interpretation of ideal power filtration ( .... ???? ....) as the "a=0" ones rather than the "b=c" (or "b=1" ... ???) ones .... ??? .....

??? diagonal as not a face .... ????? .....
