Has anyone knowledge of the first publication of the von Neumann stability analysis and its original paper?

This is some hint here.

if you have title in mind then it might help the search.

Sent you both papers this book mentions in the start. I believe this is what is originally available.

Many thanks, I received both


I know that Hirsch cited these two papers, I was also wondering if the original classified manuscript has never been published.
Thanks again

I had no idea until you mentioned it. I just searched both reference and sent to you. I believe that the original report would be in print so only few have access to it.

The reason for my question is to see the original idea of von Neumann. I want to assess that he considered the round-off error (not the discretization error) in the definition and he assumed that such error is a finite dimensional vector that is governed by the same discrete (not the continuous) equation that is solved. There is somehow confusion in literature but I always considered valid the analysis as presented by Hirsch.

Not sure if it would be anywhere in the declassified von Neumann papers. Personally I haven't browsed the collection myself.

My next trip to D.C., I'll take a peek.

I am in touch with an LA senior researcher, he wrote me about the LA-657 report of 1947.
