👉 In the context of mathematics, a "lapful" is a special case of a generalization known as the "n-dimensional Laplace operator." This operator has applications in areas such as quantum mechanics, electromagnetism, and quantum field theory. It's also used to describe various phenomena in physics, including electric circuits and electromagnetic fields.
The n-dimensional Laplace operator is defined as:
```
(-1)^n \Delta_{\mathbf{r}} = \sum_{k=0
