I do not feel confident with this proof because I did not use Ascoli-Arzela, which is used in the typical proof of Peano’s Existence Theorem.

These exist because of the Weierstrass’ theorem. Here is an extract of a work I did for University.

Oh no, there’s been an error

I don’t think that I can include all the details here without making a huge answer. Thus, do check the link at the end for notations or concepts you don’t fully understand. I commit myself to maintain the link. The proof of Peano theorem will be done using Weierstrass approximation theorem.

A good account of the different approaches that have been followed to prove this theorem can be existencce in Flett’s Differential Analysis.

In particular, the idea of using Weierstrass approximation can be attributed to Romanian mathematician Constantin Corduneanu. This completes the proof of the scalar case.
