Lebesgue constant is named after the French Mathematician, Henri Leon Lebesgue. It uses the method of interpolation and compares the function(f) with the polynomial approximation(p). It is generally expressed as Λ_{n}(T ) and its called as operator norm of X. Lebesgue interpolation constant value is 1.4359911241.. and its denoted by the symbol L_{1}.
