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

(mathematical analysis) A sequence in which each term except the first is obtained from the previous by multiplying it by a constant value, known as the common ratio of the geometric progression.

(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.

A mathematician who specializes in geometric topology.

plural of geometric topologist

A portable instrument in the form of a square frame for ascertaining distances and heights by measuring angles.

An instrument for drawing geometric curves, in which the movements of a pen or pencil attached to a revolving arm of adjustable length may be indefinitely varied by changing the toothed wheels which give motion to the arm.
