• Initial algebra — In mathematics, an initial algebra is an initial object in the category of F algebras for a given endofunctor F . The initiality provides a general framework for induction and recursion. For instance, consider the endofunctor 1+( ) on the… …   Wikipedia

• Function object — A function object, also called a functor or functional, is a computer programming construct allowing an object to be invoked or called as if it were an ordinary function, usually with the same syntax.Function objects are unrelated to functors in… …   Wikipedia

• Initial mass function — The initial mass function (IMF) is an empirical function that describes the mass distribution (the histogram of stellar masses) of a population of stars in terms of their theoretical initial mass (the mass they were formed with). The properties… …   Wikipedia

• Initial value problem — In mathematics, in the field of differential equations, an initial value problem is an ordinary differential equation together with specified value, called the initial condition, of the unknown function at a given point in the domain of the… …   Wikipedia
