This is the endpoint of the DOI resolver of the
Institute for Theoretical Physics III of the
University of Stuttgart.
Its main purpose is to serve original research papers to students of our classes, in particular old manuscripts that are hard to come by and might not even have a DOI (like many of the foundational papers of relativity by Albert Einstein).
We use it in our lecture notes and exercise assignments to provide direct download links for references.
If you enter a DOI below, the following can happen:
There are some papers in our database that do not have a DOI.
These are identified by the MD5 hash of their PDF file (which can also be submitted below).
