In mathematics, the Lambert W function, also called the omega function or product logarithm, [1] is a multivalued function, namely the branches of the converse relation of the function f(w) = we w, where w is any complex number and e w is the exponential function. The function is named after Johann Lambert, who
In mathematics, omega function refers to a function using the Greek letter omega, written ω or Ω. (big omega) may refer to: The lower bound in Big O notation, (), meaning that the function dominates in some limit
In number theory, the prime omega functions and () count the number of prime factors of a natural number . Thereby (little omega) counts each distinct prime factor, whereas the related function () (big omega) counts the total number of prime factors of , honoring their multiplicity (see arithmetic function).
The omega constant is a mathematical constant defined as the unique real number that satisfies the equation = It is the value of W(1), where W is Lambert's W function.The name is derived from the alternate name for Lambert's W function, the omega function.
The Wright omega function along part of the real axis. In mathematics, the Wright omega function or Wright function, [note 1] denoted ω, is defined in terms of the Lambert W function as: = ⌈ ⌉ ().
The standard form of the Omega ratio is a non-convex function, but it is possible to optimize a transformed version using linear programming. [4] To begin with, Kapsos et al. show that the Omega ratio of a portfolio is: = [() +] + The optimization problem that maximizes the Omega ratio is given by: [() +], (), =, The objective function is non-convex, so several ...
