Heat Conduction Equation

In two dimensions, the heat conduction equation is provided below:

∂T∂t=α(∂2T∂x2+∂2T∂y2)\frac{\partial T}{\partial t} = \alpha \left( \frac{\partial^2 T}{\partial x^2} + \frac{\partial^2 T}{\partial y^2} \right)∂t∂T=α(∂x2∂2T+∂y2∂2T)

Regarding this equation, xxx and yyy are the spatial coordinates; α\alphaα is the thermal conductivity, ttt is time and TTT represents the temperature.
