In this paper, we study the existence of solutions for Kirchhoff equation■ with mass constraint condition■ where a, b, c > 0, μ ∈ R, 2 bolev critical exponent 6 and mass critical exponent143are involved where corresponding energy functional is unbounded from below on Sc. We consider the focusing case,i.e., μ > 0 when(p, q) belongs to a certain domain in R2. We prove the existence of normalized solutions by using constraint minimization, concentration compactness principle and Minimax methods. We partially extend the results which have been studied.
