The Bogoliubov theory is extended to a Bose-Einstein condensation xvith internal degrees offreedom, realized recently it'n "Na gases where several hyperfine states are siuaaultaneotrsly cooledoptically. Starting witla a Hauaailtonian constrvxcted frouaa general gauge and spin rotation SVIIIITI(2-try principles, f'trndatnental equatiotas for condensate ?tre derived. The grotrnd state xvhere tiunereversal s3'muaaetry is brokera in soraae C2lSCS and loxv-lying collective raaodes, e..q. spin and densityxvave rauodes, are disctrssed. Novel vortex as a topological defect can be created experizaaentally.
