In multilinear algebra, a tensor contraction is an operation on a tensor that arises from the natural pairing of a finite- dimensional vector space and its dual.

In coordination chemistry and crystallography, the geometry index or structural parameter (τ) is a number ranging from 0 to 1 that indicates what the geometry of the coordination center is. The first such parameter for 5-coordinate compounds was developed in 1984. Later, parameters for 4-coordinate … See more To distinguish whether the geometry of the coordination center is trigonal bipyramidal or square pyramidal, the τ5 (originally just τ) parameter was proposed by Addison et al.: See more In 2007 Houser et al. developed the analogous τ4 parameter to distinguish whether the geometry of the coordination center is square planar or tetrahedral. The formula is: See more • A web application for determining molecular geometry indices on the basis of 3D structural files can be found here.
