Characteristic class — In mathematics, a characteristic class is a way of associating to each principal bundle on a topological space X a cohomology class of X. The cohomology class measures the extent to which the bundle is twisted particularly, whether it possesses… … Wikipedia
Characteristic 2 type — In mathematical finite group theory, a group is said to be of characteristic 2 type or even type or of even characteristic if it resembles a group of Lie type over a field of characteristic 2. In the classification of finite simple groups, there… … Wikipedia
Characteristic subgroup — In mathematics, particularly in the area of abstract algebra known as group theory, a characteristic subgroup is a subgroup that is invariant under all automorphisms of the parent group.[1][2] Because conjugation is an automorphism, every… … Wikipedia

Point groups in three dimensions — In geometry, a point group in three dimensions is an isometry group in three dimensions that leaves the origin fixed, or correspondingly, an isometry group of a sphere. It is a subgroup of the orthogonal group O(3), the group of all isometries… … Wikipedia
List of finite simple groups — In mathematics, the classification of finite simple groups states thatevery finite simple group is cyclic, or alternating, or in one of 16 families of groups of Lie type (including the Tits group, which strictly speaking is not of Lie type),or… … Wikipedia
Receiver operating characteristic — In signal detection theory, a receiver operating characteristic (ROC), or simply ROC curve, is a graphical plot of the sensitivity vs. (1 specificity) for a binary classifier system as its discrimination threshold is varied. The ROC can also be… … Wikipedia
List of spherical symmetry groups — List of symmetry groups on the sphere = Spherical symmetry groups are also called point groups in three dimensions. This article is about the finite ones.There are four fundamental symmetry classes which have triangular fundamental domains:… … Wikipedia
Euler characteristic — In mathematics, and more specifically in algebraic topology and polyhedral combinatorics, the Euler characteristic is a topological invariant, a number that describes one aspect of a topological space s shape or structure. It is commonly denoted… … Wikipedia
Euler characteristic — ▪ mathematics in mathematics, a number, C, that is a topological characteristic of various classes of geometric figures based only on a relationship between the numbers of vertices (V), edges (E), and faces (F) of a geometric figure. This… … Universalium
