**Stability of isomorphism class of deformations of Cuntz algebra**

**Abstract:**

We consider the deformations of class of *C ^{*}*-algebras generated by quadratic Wick relations. Such algebras are
deformations of well-known Cuntz algebra generated by tuples of isometries with orthogonal ranges. The sufficient
conditions for the isomorphism of deformed
