A Two Dimensional Backward Heat Problem With Statistical Discrete Data

Nguyen Dang Minh, To Duc Khanh, Nguyen Huy Tuan +1

In this paper, we focus on the backward heat problem of finding the function $\theta (x,y)=u(x,y,0)$ such that \[ {l l l} u_t - a(t)(u_{xx} + u_{yy}) & = f(x,y,t), & \qquad (x,y,t) \in Ω…
