AWARD **

**"Finding a fundamental flaw in the proof of
Fermat Last Theorem"**

*Contest goal**: Finding a fundamental error in the proposed proof
of Fermat Last Theorem^{<1>}.
Winners receive cash awards.*

*A winner can be only a registered participant.*

*In case* *if several participants* *
find errors,** the award is equally
shared between the first three.*

*An award is issued by a cheque written by a
Canadian bank in Canadian dollars in the name of a participant indicated in the
originally submitted material.*

*It is responsibility of a participant to cash the
issued cheque.*

**CONTEST RULES**

1. Those willing to participate in the contest send
their material via email shes(then add a number, the square of 13)@yahoo.ca.
The articles with a proof can be downloaded from the Internet (see the link
"Downloads" at the top of the page). In all
communications, the subject line should start
with **'FLT article'**. Contest starts from March 1, 2019.

2. Proposals should be submitted as PDF files, in English or in Russian.

3. By submitting their material, participants agree for its use in other
publications, accompanied by the appropriate reference to participants'
authorship. A participant can ask to place his / her materials on the author's
website under his / her ID *after*
the publication of contest results.

4. A ** fundamental** error is such a flaw
that makes the proposed conceptual approach

5. ** Non-Fundamental** error is such a flaw,
whose correction does not change the concept of the proof and does not challenge
its concept.

6. If a participant substantiates the validity of the proof, with his / her request and explicit permission, the participant's ID can be published on the website with such an information.

7. Additional information will appear on the author's
website ** www.shestopaloff.ca**
(see links at the top of the page). Contest info is open for free
distribution, copying and publishing in other outlets, with indication of the
