Siamese cat occasionally Siamese were born with "blue" (a cool grey) points, genetically a dilution of seal point; chocolate (lighter brown) points, a genetic variation of seal point; or lilac (pale warm gray) points, genetically a diluted chocolate. These colours were at first considered "inferior" seal points, and were not qualified for showing or breeding. All of these shades were eventually accepted by the breed associations, and became more common through breeding programmes specifically aimed at producing these colours. Later, outcrosses with other breeds developed Siamese-mix cats with points in other cat colours and patterns, including Red and Cream point, lynx (tabby)
Point process operation also used to justify the use of the Poisson point process as a mathematical of various phenomena. Point processes are mathematical objects that can be used to represent collections of points randomly scattered on some underlying mathematical space. They have a number of interpretations, which is reflected by the various types of point process notation. For example, if a point formula_1 belongs to or is a member of a point process, denoted by formula_2, then this can be written as: and represents the point process as a random set. Alternatively, the number of points of formula_2 located in some Borel
