@ Supermods: Error Correction please

Raman · 2013-02-06, 19:52

Due to an error in my own code,
I posted wrongly, verified correctly by now.

Major Corrections Please
In this thread,
http://mersenneforum.org/showthread.php?t=17736
post #3

For k = 16
Is it possible to change with the last paragraph so that it looks like

N can be written as a²+16b² if and only if
- N is not congruent to 2 (mod 4) or 8 (mod 16).
- N has no prime factors congruent to {3, 7} mod 8 to an odd power.
- If N is odd, then the sum of exponents of {5} mod 8 prime factors of N is even.

Similarly, for k = 28
please change with the last paragraph so that it looks like

N can be written as a²+28b² if and only if
- N is not congruent to 2 (mod 4) or 8 (mod 16).
- N has no prime factors congruent to {3, 5, 13, 17, 19, 27} mod 28 to an odd power.
- If N is odd, then the sum of exponents of {7, 11, 15, 23} mod 28 prime factors of N is even.

After these corrections have been made, please delete with this thread completely.

Thanks for your own time.

Minor Corrections Please
It is also being good to delete the lines saying
k = 96
k = 107
from post #9.

They are being false statements.

I verified again to check that they are not being the case,
but my own code showed them up incorrectly,
due to an use of arbitrary limit
down that way

Batalov · 2013-02-06, 20:00

Just post another one.

Raman · 2013-02-06, 20:07

Why? I don't want false statements to be present in
inside the thread, by itself.

At least please correct with those last paragraphs for
k = 16, k = 28

k = 16

N can be written as a²+16b² if and only if
- N is not congruent to 2 (mod 4) or 8 (mod 16).
- N has no prime factors congruent to {3, 7} mod 8 to an odd power.
- If N is odd, then the sum of exponents of {5} mod 8 prime factors of N is even.

k = 28

N can be written as a²+28b² if and only if
- N is not congruent to 2 (mod 4) or 8 (mod 16).
- N has no prime factors congruent to {3, 5, 13, 17, 19, 27} mod 28 to an odd power.
- If N is odd, then the sum of exponents of {7, 11, 15, 23} mod 28 prime factors of N is even.

It is a tenet of the Sciences that participates admit their mistakes.

A self-correction is always welcome, but post-editing of published errors never is.

Raman · 2013-02-06, 20:18

I hope you don't understand me.

Instead of chatting with me, you could take a moment to correct them for k = 16, k = 28 cases.

If in case that someone refers to it into the future time, then
it's being impolite to convey with false information to other people.

I could. I won't.

I hope you don't misunderstand us.

Raman · 2013-02-06, 20:29

Someone please correct them with, sincerely.

I do not want a false statement to be sandwiched between the true statements.
It's not being fair to misguide with other people.

It will take with a moment's time.

But, for this reason, the users / members can be allowed to edit with their own posts indefinitely, by itself.

Sincerely, trusting with faith

Dubslow · 2013-02-06, 20:39

What they're saying is just make another post saying that "lines x, y, and z for k = i and j in post a and b are incorrect due to a bug; instead here's the correct info: ...".

Perhaps they would consider posting a note in your message pointing to separate correction post if you were to make one.

(I'm not quite sure I agree with their methodology, but this is how you'd deal with it.)

You are barking up the wrong tree here.

You might find Dr. Andrew Lyne's experience worth noting.

Quote:

When Lyne announced the retraction of his results at a meeting of the American Astronomical Society, he received a standing ovation from his scientific colleagues for having the intellectual integrity and the courage to admit this error publicly.

This *IS* the Scientific Method in its best form.

Dubslow · 2013-02-06, 20:47

This is hardly a scientific method sort of thing though; this is just a bug found in code, that is now fixed. It's not like he's retracting a major claim or study or anything. (Also note this is mathematics, not science; it is logical and provably correct, as opposed to scientific empiricism which is not.)

Raman · 2013-02-06, 20:52

I have posted again with the corrected versions
for k = 16, k = 28 cases, inside
in that same thread, by me itself.

Can a super-mod right now please remove
with those incorrect versions, from old post?

I can't believe I need to fight / argue very much
with super-mods in order to correct with my own
errors, by me itself,

from within my own post, by itself
