Definition df-cpmat 20330

Description: The set of all constant polynomial matrices, which are all matrices whose entries are constant polynomials (or "scalar polynomials", see ply1sclf 19476). (Contributed by AV, 15-Nov-2019.)

Assertion

Ref	Expression
df-cpmat	⊢ ConstPolyMat = (𝑛 ∈ Fin, 𝑟 ∈ V ↦ {𝑚 ∈ (Base‘(𝑛 Mat (Poly1‘𝑟))) ∣ ∀𝑖 ∈ 𝑛 ∀𝑗 ∈ 𝑛 ∀𝑘 ∈ ℕ ((coe1‘(𝑖𝑚𝑗))‘𝑘) = (0g‘𝑟)})

Distinct variable group:   𝑖,𝑗,𝑘,𝑚,𝑛,𝑟
