Theorem mhprcl 22090

Description: Reverse closure for homogeneous polynomials, use elfvov1 7402 and elfvov2 7403 with reldmmhp 22084 for the reverse closure of 𝐼 and 𝑅. (Contributed by SN, 4-Aug-2025.)

Hypotheses

Ref	Expression
mhprcl.h	⊢ 𝐻 = (𝐼 mHomP 𝑅)
mhprcl.x	⊢ (𝜑 → 𝑋 ∈ (𝐻‘𝑁))

Assertion

Ref	Expression
mhprcl	⊢ (𝜑 → 𝑁 ∈ ℕ0)

Proof of Theorem mhprcl

Dummy variables 𝑓 𝑔 ℎ 𝑛 are mutually distinct and distinct from all other variables.
