SUMMARY
The discussion focuses on verifying whether the function $$e^{-0.5x^2}$$ is an eigenfunction of the operator $$\frac{d^2}{dx^2}-x^2$$. The analysis reveals that applying the operator results in $$e^{-0.5x^2}(x^2-1)-x^2$$, indicating that $$e^{-0.5x^2}$$ does not satisfy the eigenfunction condition. The operator is clearly defined as $$\left(\frac{d^2}{dx^2}-x^2\right)f(x)=\frac{d^2f(x)}{dx^2}-x^2f(x)$$.
