    Title: Local theta lifts for p-adic unitary dual pairs U(2)×U(1),U(2)×U(3) and a p-adic quaternionic dual pair U(1)×U(1).
    abstract: In this paper we describe the local theta lift for p-adic unitary dual pairs U(2)×U(1) and U(2)×U(3).
          Also we describe the local theta lift for a p-adic quaternionic unitary dual pair U(1)×U(1).
