notes from discussion with alex today

... we wondered whether, for example, rees algebra (??? ...) associated with ideal power filtration of certain (?? ...) ideal in cocone (?? corresponding to some infinitesimal but perhaps "irregular" neighborhood of the "basepoint" of the corresponding affine toric variety ... ??? ...) might relate to subdivision of corresponding cone in certain corresponding way ..... ????? ....... ????? .....

?? also tried to relate something like "standard blow-up of basepoint" to something like "barycentric subdivision" .... ??? at one point i thought that syzygy might get involved, but then thought that maybe it was just a relation ..... ???? ......

?? point in cone giving grading of cocone .... ???? .......

?? classifying monoided topos for quasicoherent action .... ???? ... ???? ?? explicit description ... ??? ... non-toric version as well .... ???? ....
