Theorem mplsubglem 21115

Description: If 𝐴 is an ideal of sets (a nonempty collection closed under subset and binary union) of the set 𝐷 of finite bags (the primary applications being 𝐴 = Fin and 𝐴 = 𝒫 𝐵 for some 𝐵), then the set of all power series whose coefficient functions are supported on an element of 𝐴 is a subgroup of the set of all power series.

Distinct variable groups:   𝑓,𝑔,𝑥,𝑦, 0   𝐴,𝑓,𝑔,𝑥,𝑦   𝐵,𝑓,𝑔   𝐷,𝑔   𝑓,𝐼   𝜑,𝑥,𝑦   𝑆,𝑓,𝑔,𝑦

Allowed substitution hints:   𝜑(𝑓,𝑔)   𝐵(𝑥,𝑦)   𝐷(𝑥,𝑦,𝑓)   𝑅(𝑥,𝑦,𝑓,𝑔)   𝑆(𝑥)   𝑈(𝑥,𝑦,𝑓,𝑔)   𝐼(𝑥,𝑦,𝑔)   𝑊(𝑥,𝑦,𝑓,𝑔)

Proof of Theorem mplsubglem

Dummy variables 𝑘 𝑢 𝑣 are mutually distinct and distinct from all other variables.
