61Matrix addition — In mathematics, matrix addition is the operation of adding two matrices by adding the corresponding entries together. However, there are other operations which could also be considered as a kind of addition for matrices, the direct sum and the… …
62Combinatorial species — In combinatorial mathematics, the theory of combinatorial species is an abstract, systematic method for analysing discrete structures in terms of generating functions. Examples of discrete structures are (finite) graphs, permutations, trees, and… …
63Matrix theory — is a branch of mathematics which focuses on the study of matrices. Initially a sub branch of linear algebra, it has grown to cover subjects related to graph theory, algebra, combinatorics, and statistics as well.HistoryThe term matrix was first… …
64Clique problem — The brute force algorithm finds a 4 clique in this 7 vertex graph (the complement of the 7 vertex path graph) by systematically checking all C(7,4)=35 4 vertex subgraphs for completeness. In computer science, the clique problem refers to any of… …
65Building (mathematics) — In mathematics, a building (also Tits building, Bruhat–Tits building) is a combinatorial and geometric structure which simultaneously generalizes certain aspects of flag manifolds, finite projective planes, and Riemannian symmetric spaces.… …

67Conversation analysis — (commonly abbreviated as CA) is the study of talk in interaction (both verbal and non verbal in situations of everyday life). CA generally attempts to describe the orderliness, structure and sequential patterns of interaction, whether… …
68Incidence matrix — In mathematics, an incidence matrix is a matrix that shows the relationship between two classes of objects. If the first class is X and the second is Y, the matrix has one row for each element of X and one column for each element of Y. The entry… …
69Binary matrix — In mathematics, particularly matrix theory, a binary matrix or (0,1) matrix is a matrix in which each entry is either zero or one. For example::egin{pmatrix}0 11 0end{pmatrix} is a 2 × 2 binary matrix.Frequently operations on binary matrices are …
