  2. Projective line over a ring - Wikipedia

    en.wikipedia.org/wiki/Projective_line_over_a_ring

    Consider P 1 (Z / nZ) when n is a composite number.If p and q are distinct primes dividing n, then p and q are maximal ideals in Z / nZ and by Bézout's identity there are a and b in Z such that ap + bq = 1, so that U[p, q] is in P 1 (Z / nZ) but it is not an image of an element under the canonical embedding.

  3. B'z - Wikipedia

    en.wikipedia.org/wiki/B'z

    To commemorate the occasion, the "B'z 20" campaign was launched that saw two further compilation albums: B'z The Best "Ultra Pleasure" was released on June 18, 2008, and featured the greatest of the band's hits on a two-disc collection in chronological order, along with two all-new modern recordings of older tracks, while B'z The Best "Ultra ...

  4. Beal conjecture - Wikipedia

    en.wikipedia.org/wiki/Beal_conjecture

    The case (x, y, z) = (3l, 3m, n) is direct for l, m ≥ 2 and n ≥ 3 from work by Kraus. [ 32 ] The Darmon–Granville theorem uses Faltings's theorem to show that for every specific choice of exponents ( x , y , z ), there are at most finitely many coprime solutions for ( A , B , C ).

  5. Affine cipher - Wikipedia

    en.wikipedia.org/wiki/Affine_cipher

    In this encrypting example, [1] the plaintext to be encrypted is "AFFINE CIPHER" using the table mentioned above for the numeric values of each letter, taking a to be 5, b to be 8, and m to be 26 since there are 26 characters in the alphabet being used.

  6. Multiplicative group of integers modulo n - Wikipedia

    en.wikipedia.org/wiki/Multiplicative_group_of...

    Integer multiplication respects the congruence classes, that is, a ≡ a' and bb' (mod n) implies ab ≡ a'b' (mod n). This implies that the multiplication is associative, commutative, and that the class of 1 is the unique multiplicative identity.

  7. m,n,k-game - Wikipedia

    en.wikipedia.org/wiki/M,n,k-game

    Example of a completed 11,10,5-game. An m,n,k-game is an abstract board game in which two players take turns in placing a stone of their color on an m-by-n board, the winner being the player who first gets k stones of their own color in a row, horizontally, vertically, or diagonally.

  8. Trilinear coordinates - Wikipedia

    en.wikipedia.org/wiki/Trilinear_coordinates

    If the parameters l, m, n respectively equal the side lengths a, b, c (or the sines of the angles opposite them) then the equation gives the circumcircle. [1]: p. 199 Each distinct circumconic has a center unique to itself. The equation in trilinear coordinates of the circumconic with center x' : y' : z' is [1]: p. 203

  9. Least common multiple - Wikipedia

    en.wikipedia.org/wiki/Least_common_multiple

    A multiple of a number is the product of that number and an integer. For example, 10 is a multiple of 5 because 5 × 2 = 10, so 10 is divisible by 5 and 2. Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2.
