Abstract
For any atomless positive measure μ, the space L 1(μ) has the polynomial Daugavet property, i.e., every weakly compact continuous polynomial \({P:L_1(\mu)\longrightarrow L_1(\mu)}\) satisfies the Daugavet equation \({\|{\rm Id} + P\|=1 + \|P\|}\). The same is true for the vector-valued spaces L 1(μ, E), μ atomless, E arbitrary.
