Partial group algebra

A partial group algebra is an associative algebra related to the partial representations of a group.

Examples

The partial group algebra $\mathbb{C}_{\text{par}}\left(\mathbb{Z}_4\right)$ is isomorphic to the direct sum:^[1]
$\mathbb{C}\oplus \mathbb{C}\oplus\mathbb{C}\oplus\mathbb{C}\oplus\mathbb{C}\oplus\mathbb{C}\oplus\mathbb{C}\oplus M_2\left(\mathbb{C}\right) \oplus M_3\left(\mathbb{C}\right)$
