(mathematics) A measure of central tendency of a set of n values computed by extracting the nth root of the product of the values.

(mathematical analysis) Any infinite series whose terms are in geometric progression; any series of the form a+ar+ar²+ar³⋯=a∑ᵢ₌₀ ᪲rⁱ.

(chemistry, dated, deprecated by IUPAC) either the cis- or trans- isomer of a compound that exhibits geometric isomerism

(chemistry, dated, deprecated by IUPAC) A form of isomerism in which, in one isomer two atoms or groups are on the same side of the plane of a double bond or ring, whereas in the other isomer they are on opposite sides; these are cis- and trans- isomers, respectively.

(mathematical analysis, geometry, topology) A branch of mathematics in which techniques from differential geometry are used in the analysis and solution of partial differential equations, and vice versa.

(linear algebra) The dimension of the eigenspace of a given eigenvalue (of a given square matrix).

A mathematician who specializes in geometric topology.

plural of geometric mean

plural of geometric distribution

Either of two slightly different discrete probability distributions, each based on repetitions of a trial with "success" probability p: (1) the number X of trials required to obtain one success, or (2) the number Y = X − 1 of failed trials before the first success.
