On functions whose graph is a Hamel basis. (English) Zbl 1012.15001

Real valued Hamel functions are considered. The additivity condition of a function \(f(x,y)\) is studied. The representation of a function as a sum of two Hamel functions is discussed. It is shown that every function is the pointwise sum of two Hamel functions. A connection of this statement with function additivity is given.
