tærer

Tårer (Danish for "teardrops") is a concept within Danish mathematics that deals with the symmetry of certain geometric figures, particularly those related to chevrons and isosceles triangles. The theory was developed in the early 20th century by Danish mathematicians.

A tårere (tearay) in mathematics is a geometric shape that features multiple types of symmetry, specifically rotational and radial symmetry. A tårere is defined as an ordulative figure, with tangential symmetry about a generatrix. In simpler terms, a tårere is a geometric shape that exhibits symmetry in both its shape and its arrangement of lines or patterns.

The study of tårer gained significant attention in Denmark during the interwar period due to the innovative work of Danish mathematicians who developed new methods to represent geometric patterns. Tårer are now recognized within the context of modern mathematics for their unique properties and their implications in various areas of the field.

Applications of tårer have appeared in physics and computer graphics. Particularly, tårer patterns demonstrate their usefulness in introducing variance in designs, thus making them more realistic via reproduction in graphic art.
