## Safe Primes, in RSA

Ok, let's try to discuss here: https://wiki.alquds.edu/?query=Talk:RSA_(cryptosystem)#Safe_Primes,_in_RSA_Key_Generation No "reliable sources" are needed here. Here you just need to think with your own head. This is math. In any case, I do not owe you anything, and I do not demand anything from you.

## Speedy deletion declined: Trignonmetric Ratios

Hello D.Lazard. I am just letting you know that I declined the speedy deletion of Trignonmetric Ratios, a page you tagged for speedy deletion, because of the following concern: Not a recently created redirect - consider WP:RfD. Thank you. Ivanvector (Talk/Edits) 18:30, 14 April 2023 (UTC)

In Inverse element#In rings, the set of all functions from the integers to the integers with the operations of pointwise addition and multiplication is not an example of a ring in which some elements have more than one left inverse. Probably this is not what is meant anyway since at the beginning of the paragraph one restricts to noncommutative rings, however it is not obvious how to understand it. If it is meant that the ring is the monoid ring ${\displaystyle R[M]}$ of the monoid ${\displaystyle M}$ of all functions from the integers to the integers and the ring ${\displaystyle R}$ being the integers, perhaps it should be written so.

## Dispute arbitration concerning the Dual numbers article

We disagree and I'm impatient for a 3rd opinion. I've started this Wikipedia:Dispute resolution noticeboard - Wikipedia. I don't know how the process is going to happen.  The dispute page currently asks us to "keep discussion to a minimum" until someone intervenes. Svennik (talk) 20:20, 26 April 2023 (UTC)
