    Abstract. Let \(d\in\mathbb{N}\) and let \(\boldsymbol{\alpha}=(\alpha_1,\dots,\alpha_d)\in(0,1)^d\). We prove that the algebraic direct sum \[ \mathcal{G}_{\boldsymbol{\alpha}}^{\mathrm{alg}} := \bigoplus_{\mathbf{k}\in\mathbb{N}_0^d}\mathbb{C}e_{\mathbf{k}}, \quad e_{\mathbf{k}}(x) := \prod_{j=1}^d \frac{x_j^{k_j\alpha_j}}{\Gamma(k_j\alpha_j+1)}, \] is the canonical multi-graded monomial space on which the partial Riemann–Liouville integrals \( J_j:={}_0 I_{x_j}^{\alpha_j} \text{ for } 1\le j\le d \) and the partial Caputo derivatives …
