6. Higher-Dimensional Schrödinger Equation:

In quantum mechanics, the time-dependent Schrödinger equation can be extended to $�$ -dimensional space: $� ℏ \frac{\partial Ψ (�, �)}{\partial �} = - \frac{ℏ^{2}}{2 �} \nabla^{2} Ψ (�, �) + � (�, �) Ψ (�, �)$ where $�$ represents a vector in $�$ -dimensional space.

7. Higher-Dimensional Diffusion Equation:

The diffusion equation in $�$ -dimensions can be written as: $\frac{\partial � (�, �)}{\partial �} = � \nabla^{2} � (�, �)$ where $� (�, �)$ represents the concentration at point $�$ and time $�$ , and $�$ is the diffusion coefficient.

These equations illustrate the extension of popular computational concepts into higher-dimensional spaces.
