aybx
AyBx is a notation that appears in various mathematical and technical contexts without a single, universal definition. In general, it is used to denote a quantity that depends on two indices or parameters, often written as a two-parameter family or a two-dimensional array. The exact meaning of AyBx is determined by the surrounding context and should be clarified in the source where it is introduced.
Common interpretations include:
- as a value of a function f defined on a product set Y×X, with AyBx representing the
- as an entry in a two-dimensional structure, where the row is indexed by y and the column
- as a product or combination of two parameterized families, such that AyBx encodes a quantity derived
Because AyBx is not standardized, authors typically define it explicitly at first use to avoid ambiguity. For
