In computability theory, the Ackermann function, named after Wilhelm Ackermann, is one of the simplest [1] and earliest-discovered examples of a total computable function that is not primitive recursive. All primitive recursive functions are total and computable, but the Ackermann function illustrates that not all total ... See also inverse Ackermann function.

A(x,y,z) was simplified to a function of 2 variables ...State Feedback Gain Matrix 'K' And Ackermann's Formula (Problem) (Digital Control Systems)

2006-01-3638. Ackermann steering geometry relates the steer angle of an inside tire to that of the outside tire. When turning the inside tire travels a shorter radius than the outside tire and thus must have a greater steer angle to avoid tire scrub. Classic Ackermann minimizes scrub by positioning both tires perpendicular to the turn center.
