Abstract. In this paper we investigate the existence and uniqueness for the solution of the problem of determining the $v=(v_{0},v_{1},v_{2})$ in the quasilinear parabolic equation $\frac{\partial y}{\partial t}
- \sum_{i=1}^{n} \frac{\partial }{\partial x_{i}...
...
+\sum_{i=1}^{n} B_{i}(y,v_{1}) \frac{\partial y}{\partial x_{i}}=f(x,t,v_{2})
$. For the objective functional $ J_{\beta}(v)= \int_{S} [y(\zeta,t) - f_{0}(\zeta,t)]^{2} d\zeta dt + \beta \sum_{m=0}^{2} \Vert v_{m}-\omega_{m}\Vert^{2}_{l_{2}},$ it is proven that the problem has at least one solution for $\beta \ge 0$, and has a unique solution for $\beta > 0$.
