YxK

YxK is a compact alphanumeric designation encountered in several unrelated domains. It does not refer to a single, universally recognized concept; its meaning is defined by context.

In mathematics and logic, the expression Y × K denotes the Cartesian product of sets Y and K. When written in plain text as YxK, it is used in informal notes or programming pseudocode to indicate pairs (y, k) with y in Y and k in K.

In data representation and computer science, YxK is sometimes used to describe a two-dimensional array or matrix with Y rows and K columns. This usage is common in algorithm descriptions and tutorials where explicit multiplication is not shown.

In product naming and model codes, some vendors assign YxK as a model or version code, where letters and numbers denote different features, revisions, or configurations. The exact specification depends on the issuing organization.

In culture and media, YxK may appear as an acronym or stylized title in works of fiction or branding, again without a universal fixed meaning.

Disambiguation: When encountering YxK, readers should look for clarifying information such as accompanying variables, dimensions, dates, or domain identifiers to determine which meaning applies.
