abstract = {<p style="text-align: justify;">In this paper, we study shrinking gradient Ricci solitons whose Ricci tensor
has one eigenvalue of multiplicity at least $n−2.$ Firstly, we show that if the minimal
eigenvalue of Ricci tensor has multiplicity at least $n−1$ at each point, then the soliton
are Einstein. While on the shrinking gradient Ricci solitons whose maximal eigenvalue
has multiplicity at least $n−1,$ the triviality are also true if we naturally require the
positivity of Ricci tensor.<br/>We further prove that if the maximal (or minimal) eigenvalue of Ricci tensor has multiplicity at least $n−2$ at each point , and in addition the sectional curvature is bounded
from above, then the soliton are Einstein.</p>},
