61Homogeneous space — In mathematics, particularly in the theories of Lie groups, algebraic groups and topological groups, a homogeneous space for a group G is a non empty manifold or topological space X on which G acts continuously by symmetry in a transitive way. A… …
62Thematic Apperception Test — The Thematic Apperception Test is an example of a projective test.Historically, the Thematic Apperception Test or TAT has been amongst the most widely used, researched, and taught projective psychological tests. Its adherents claim that it taps a …
63Algebraic K-theory — In mathematics, algebraic K theory is an important part of homological algebra concerned with defining and applying a sequence Kn(R) of functors from rings to abelian groups, for all integers n. For historical reasons, the lower K groups K0 and… …
64Lie sphere geometry — is a geometrical theory of planar or spatial geometry in which the fundamental concept is the circle or sphere. It was introduced by Sophus Lie in the nineteenth century. [The definitive modern textbook on Lie sphere geometry is Harvnb|Cecil|1992 …
65Translation plane — In mathematics, a translation plane is a particular kind of projective plane, as considered as a combinatorial object. [Projective Planes [http://www.maths.qmul.ac.uk/ pjc/pps/pps2.pdf On projective planes] ] In a projective plane, scriptstyle p… …
66Resolution of singularities — Strong desingularization of Observe that the resolution does not stop after the first blowing up, when the strict transform is smooth, but when it is simple normal crossings with the exceptional divisors. In algebraic geometry, the problem of… …
67Hyperplane — A hyperplane is a concept in geometry. It is a higher dimensional generalization of the concepts of a line in Euclidean plane geometry and a plane in 3 dimensional Euclidean geometry. The most familiar kinds of hyperplane are affine and linear… …
68Group representation — In the mathematical field of representation theory, group representations describe abstract groups in terms of linear transformations of vector spaces; in particular, they can be used to represent group elements as matrices so that the group… …
69Rorschach inkblot test — The Rorschach inkblot test (pronounced IPA2|ʁoɐʃax) is a method of psychological evaluation. Psychologists use this test to try to examine the personality characteristics and emotional functioning of their patients. The Rorschach is currently the …
70Canonical bundle — In mathematics, the canonical bundle of a non singular algebraic variety V of dimension n is the line bundle which is the nth exterior power of the cotangent bundle Ω on V. Over the complex numbers, it is the determinant bundle of holomorphic n… …
