This problem appears naturally of weak and pointwise sentinel with a small or singleton region observation. The main tool is a theorem of uniqueness of the solution of ill-posed Cauchy problem for the parabolic equation.</p>}, number={2}, journal={Innovative Journal of Mathematics (IJM)}, author={Imad, Rezzoug and Lamya, Merabti Nesrine}, year={2022}, month={Apr.}, pages={44–62} }
