A grid is drawn up, and each cell is split diagonally. The two multiplicands of the product to be calculated are written along the top and right side of the lattice, respectively, with one digit per column across the top for the first multiplicand (the number written left to right), and one digit per row down the right side for the second multiplicand (the number written top-down).
Historically the grid calculation (tweaked slightly) was the basis of a method called lattice multiplication, which was the standard method of multiple-digit multiplication developed in medieval Arabic and Hindu mathematics.
In mathematics, informally speaking, Euclid's orchard is an array of one-dimensional "trees" of unit height planted at the lattice points in one quadrant of a square lattice. [1] More formally, Euclid's orchard is the set of line segments from ( x , y , 0) to ( x , y , 1) , where x and y are positive integers .
In the study of Diophantine geometry, the square lattice of points with integer coordinates is often referred to as the Diophantine plane. In mathematical terms, the Diophantine plane is the Cartesian product Z × Z {\displaystyle \scriptstyle \mathbb {Z} \times \mathbb {Z} } of the ring of all integers Z {\displaystyle \scriptstyle \mathbb {Z} } .
In the geometry of numbers, the subspace theorem was obtained by Wolfgang M. Schmidt in 1972. [6] It states that if n is a positive integer, and L 1,...,L n are linearly independent linear forms in n variables with algebraic coefficients and if ε>0 is any given real number, then the non-zero integer points x in n coordinates with
A lattice is an abstract structure studied in the mathematical subdisciplines of order theory and abstract algebra.It consists of a partially ordered set in which every pair of elements has a unique supremum (also called a least upper bound or join) and a unique infimum (also called a greatest lower bound or meet).
