Boris Schein
Boris Moiseyevich Schein (22 June 1938 – 4 October 2023) was a Russian-American mathematician, an expert in semigroups, and a Distinguished Professor in the Department of Mathematical Sciences at the University of Arkansas.. Biography Schein was born in Moscow on 22 June 1938, and moved to Saratov during World War II. He became interested in mathematics as a teenager, and came under the influence of Viktor Wagner, a professor of mathematics at Saratov State University. Schein did his undergraduate studies in Mechanics-Mathematics at Saratov State, and chose to specialize in geometry, Wagner's subject. In 1958 he solved the problem of characterizing the semigroups that could be embedded into an inverse semigroup. He graduated summa cum laude in 1960. He continued working as a graduate student with Wagner, and in 1962 defended a candidacy dissertation on semigroups of transformations at the Herzen State Pedagogical University of Russia in Saint Petersburg.

Marcel Dekker
Marcel Dekker was a journal and encyclopedia publishing company with editorial boards found in New York City.

Ki-Hang Kim
Ki-Hang Kim (; 5 August 1936 – 15 January 2009), also known as Kim Ki-Hang Butler, Hang Kim, Keyhany Keem, or Kim Ki-Hang was a Korean-American Mathematician and Alabama State University professor known for his contributions in semigroups, Boolean matrices, and Social Sciences. He frequently co-wrote with Fred Roush. Personal life Kim was born in Anju, Korea, Empire of Japan (now in North Korea) the eldest son of independent farmers Jin Gyong Kim and Mayhryn Hong. A bright child, by 12 years old Kim was capable of speaking some Japanese, Chinese, English and Russian, and had skipped some grades of school; by 14, he was acting as an interpreter for US troops in Korea during the Korean War. In 1950, Kim's region was held by the South Korean and American army. When the North Koreans and Chinese returned, Kim was given six hours to decide whether to take an empty U.S. Air Force seat, and go South with the US Army, which he accepted upon the urging of his father. He didn't see his ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Outer Product
In linear algebra, the outer product of two coordinate vectors is the matrix whose entries are all products of an element in the first vector with an element in the second vector. If the two coordinate vectors have dimensions ''n'' and ''m'', then their outer product is an ''n'' × ''m'' matrix. More generally, given two tensors (multidimensional arrays of numbers), their outer product is a tensor. The outer product of tensors is also referred to as their tensor product, and can be used to define the tensor algebra. The outer product contrasts with: * The dot product (a special case of "inner product"), which takes a pair of coordinate vectors as input and produces a scalar * The Kronecker product, which takes a pair of matrices as input and produces a block matrix * Standard matrix multiplication Definition Given two vectors of size m \times 1 and n \times 1 respectively :\mathbf = \begin u_1 \\ u_2 \\ \vdots \\ u_m \end, \quad \mathbf = \begin v_1 \\ v_2 \\ \vdots \\ v_n \en ...

Binary Relation
In mathematics, a binary relation associates some elements of one Set (mathematics), set called the ''domain'' with some elements of another set called the ''codomain''. Precisely, a binary relation over sets X and Y is a set of ordered pairs (x, y), where x is an element of X and y is an element of Y. It encodes the common concept of relation: an element x is ''related'' to an element y, if and only if the pair (x, y) belongs to the set of ordered pairs that defines the binary relation. An example of a binary relation is the "divides" relation over the set of prime numbers \mathbb and the set of integers \mathbb, in which each prime p is related to each integer z that is a Divisibility, multiple of p, but not to an integer that is not a Multiple (mathematics), multiple of p. In this relation, for instance, the prime number 2 is related to numbers such as -4, 0, 6, 10, but not to 1 or 9, just as the prime number 3 is related to 0, 6, and 9, but not to 4 or 13.
