Coherent States with SU(2) and SU(3) Charges
  We define coherent states carrying SU(2) charges by exploiting Schwinger boson representation of SU(2) Lie algebra. These coherent states satisfy continuity property and provide resolution of identity on $S^{3}$. We further generalize these techniques to construct the corresponding SU(3) charge coherent states. The SU(N) extension is discussed.
