EITHER

    Q.E.D. (also written QED and QED) is an initialism of the Latin phrase quod erat demonstrandum, meaning "what was to be demonstrated," 
    or without Latin borrowings, "what was to be shown."


    Wikipedia, https://en.wikipedia.org/wiki/Q.E.D.


OR  simply


    "The proof is completed".

And after that the words of "Thanks" to those who tauched you, who pointed you the idea of the proof, helped to identify the sources,
who inspired you, who heard and corrected your preliminary versions, and who supported you etc.
