Our aim in this article is to contribute to the theory of Lipschitz free p-spaces for 0 < p≤ 1 over the Euclidean spaces Rd and Zd. To that end, we show that Fp(Rd) admits a Schauder basis for every p∈ (0 , 1] , thus generalizing the corresponding result for the case p= 1 by Hájek and Pernecká (J Math Anal Appl 416(2):629–646, 2014, Theorem 3.1) and answering in the positive a question that was raised by Albiac et al. in (J Funct Anal 278(4):108354, 2020). Explicit formulas for the bases of Fp(Rd) and its isomorphic space Fp([0 , 1] d) are given. We also show that the well-known fact that F(Z) is isomorphic to ℓ1 does not extend to the case when p< 1 , that is, Fp(Z) is not isomorphic to ℓp when 0 < p< 1.
