[P] pseudoprimes in Z(i) (c0ntd) by akdevaraj May 1How to find other bases which will render 21 a pseudoprime in Z(i)?
Sum of coefficients in this case is 22.Split 22 into two parts
such that one is divisible by 3 and the other by 7. Example: 15 and 7.
Then 15 +7i is a suitable base.
[P] pseudoprimes in Z(i) by akdevaraj Apr 30How to construct pseudoprimes in Z(i)? Let ab be a composite number where
a and b are prime. Then ab is a pseudoprime to the base
ab + i. Example: 3*7 = 21. 21 is a pseudoprime to base 21 + i.i.e.
((21 + i )^20 -1)/21 yields a Gaussian integer as quotient. Minor variations
will be illustrated in the next message.
[P] Fermat's theorem in Z(i) by akdevaraj Apr 29If we were to look upon the complex plane as a lattice with
horizontal lines representing real numbers and vertical ones as imaginary
ones any lattice point represents a Gaussian integer. These are
suitable bases for Fermat's theorem subject to two conditions: a)
the primes should be of form 4m + 1 b) the Gaussian integer should not be co-prime with
a prime factor of the prime chosen.
Examples: let 2 + I be the base then it is suitable for primes
17, 29 etc.

[P] Pointless by jeremyboden Apr 15a/0 is the same thing as a/1
I advise you to give up this division by zero idea.
[p] figures by pahio Apr 15Dear unlord,
It's nice to hear that there exists a solution to that character
problem. Of course there are here other, bigger problems -- one
of the hardest ones is perhaps formed by the figures (graphs etc.)
in the PlanetMath articles.
re: special math characters by unlord Apr 12OK, this is not good news, but at least there is a fix.
The problem has to do with the special database encoding that is needed to make these special characters work. It was set up correctly on the old server, and for some reason I thought, or rather imagined, that it would work well on the new server. More work will have to be done to fix it. However, having done it once -- in the distant past -- I can figure out how to do it again.
Thanks for letting me know.>
special math characters by pahio Apr 2Hi admins, the math fraktur letters \mathfrak{ } and the math
calligraphy letters \mathcal{ } are not visible in the entries -- one sees them only
as question marks (see e.g. the entry "algebraic number theory").
In the entry "ideal multiplication laws" you see much such question
marks!>
[p] SEARCH MACHINE by pahio Feb 20Hi admins, the search machine does not work. Please start it again!
[P] A bit of history by akdevaraj Feb 20Before giving further comments on Fermat's theorem and
related matters let me give a bit of history:
1640 Fermat's theorem
1740(circa) Euler's generalisation of FT
2004 Euler's generalisation of FT - a further generalisation (Devaraj))
2006 Minimum Universal exponent generalisation of Fermat's T. (Devaraj).
2012 Ultimate generalisation of FT -Pahio and Devaraj
My paper " Euler's generalisation......." freed FT of the requirement of
base and exponent to be coprime. Secondly we can identify small factors of
very large numbers by merely operating on the exponents.
Before concluding this message I would like to thank Pahio for enabling
ültimate generalisation of FT.
[P] Euler's generalisation of Fermat's theorem in k(i) (contd) by akdevaraj Feb 19Before generalising let me give another related example:
((15 + 7*I)^12-1)/21 also yields a Gaussian integer as quotient.
[P] Euler's generalisation of Fermat's theorem in k(i) by akdevaraj Feb 18I will just give an example to illustrate:
((21+i)^12-1)/21 is a Gaussian integer. Needless to say
we can verify this only if we have pari or similar
software.
General Method for Summing Divergent Series by Sinisa Feb 17I discovered general method for summing divergent series, which we can also consider as a method for
computing limits of divergent sequences and functions in divergent points, In this case, limits of
sequences of their partial sums. I applied the method to compute the value of some divergent integrals.
