## Number theory

Use this thread to discuss the Number theory page.

• I have no idea what "unit" means that "integer" doesn't cover, and that's covered by mulna'u (see Abstract Algebra). --rlpowell

• A unit in an integral domain is a number that every number is divisible by; e.g. the units in Z are 1 and -1, and the units in the Gaussian integers are 1, i, -1, and -i. -phma

Oh, OK. This should all have gone in discuss, sorry. My bad.

Here's the discussion that was on the page before I cleaned it up:

• prime: cmuna'ux1 is a prime number in integral domain x2
• I'd consider that to mean "unit" and not "prime". I suggest:
• prime: ralju namcu: ralna'un1=r1 is a prime number in integral domain r2
• Something more like zilterfendi, i should think...
• unit: jicmu namcu: cmuna'un1=j1 is a unit of integral domain j2
• I have no idea what "unit" means that "integer" doesn't cover, and that's covered by mulna'u (see Abstract Algebra). --rlpowell
• A unit in an integral domain is a number that every number is divisible by; e.g. the units in Z are 1 and -1, and the units in the Gaussian integers are 1, i, -1, and -i. -phma
• "prime" is clearly something with selci. Furthermore, it's clearly a mulna'u; I suggest mulna'usle, which I'll now go put in jbovlaste --rlpowell
• ko'a goi lo na pilji be ko'e bei ko'e goi lo kantu namcu na du ko'a

The original text of the page had:

n1=j1 is a unit of integral domain j2

for cmuna'u, but that's not what arj entered on jbovlaste. Is this likely to be a problem?
