Partial group algebra
In mathematics, a partial group algebra is an associative algebra related to the partial representations of a group. == Examples == The partial group algebra C par ( Z 4 ) {\displaystyle \mathbb {C} _{\text{par}}(\mathbb {Z} _{4})} is isomorphic to the direct sum: C ⊕ C ⊕ C ⊕ C ⊕ C ⊕ C ⊕ C ⊕ M 2 C ⊕ M 3 C {\displaystyle \mathbb {C} \oplus \mathbb {C} \oplus \mathbb {C} \oplus \mathbb {C} \oplus \mathbb {C} \oplus \mathbb {C} \oplus \mathbb {C} \oplus \mathrm {M} _{2}\mathbb {C} \oplus \mathrm {M} _{3}\mathbb {C} } == See also == Group ring Group representation == Notes == == References == Exel, Ruy (1998).
