【创源大讲堂】A TIGHT UPPER BOUND ON THE NUMBER OF NON-ZERO WEIGHTS OF A CONSTACYCLIC CODE
摘要：For a simple-root lambda-constacyelic code C over F_q, let <ρ>(resp. <ρ,M>) be the subgroup of the automorphism group of C generated by the cyclic shift ρ (resp. the subgroup generated by the cyclic shift ρ and the scalar multiplication group M). Let N_G(C^*) be the mumber of orbits of a subgroup G of the automorphism group of C acting on C^* = C\{0}. In this talk, we show explicit formulas ...
