# Talk:Ill-posed problems

From Encyclopedia of Mathematics

Typos fixed during TeXing

- In paragraph starting "The so-called smoothing functional...", replaced $R_2[u,\alpha]$ by $R_2(u,\alpha)$

Typographical changes

- Removed some redundant curly brackets (braces), eg, $\{\Omega[z]\}^{1/2}$ becomes $\Omega[z]^{1/2}$
- Some complicated inline formulae are now displayed, eg, the integral whose minimum is the solution to the spline problem.
