Definitions
Noun
- 1 A natural number that is the product of two (not necessarily distinct) prime numbers.
"Again, to be perfectly clear, we are looking for c values that produce a low density of semiprimes when employing Euler's basic polynomial but changing the c values, in the range of x=1 to 10000. Some very early standouts are: c=4 which produces 799 semiprimes; c=6 which produces 532 semiprimes; c=12 which produces only 431 semiprimes; c=18 which produces 364 semiprimes, and c=30 which produces only 320 semiprimes."
Adjective
- 1 That has properties derived directly or by extension from a semiprime. not-comparable
"The final part of the semiprime-semisimple analogy is given by Proposition 4.4. A ring #92;mathbf#123;R#125; is semiprime if and only if #92;mathbf#123;R#125; is isomorphic to a subdirect product of prime rings."
