Due to the increasing importance of knowledge, private firms and public institutions such as universities, colleges and research institutes have discovered the importance of protecting and managing their intellectual prop...

We prove that the class of functions with the Baire property has the weak difference property in category sense. That is, every function for which f(x+h)−f(x) has the Baire property for every h ∈ R can be written in the form f = g+H+φ where g has the Baire property, H is additive, and for every h ∈ R we have φ(x+h)−φ(x) 6= 0 only on a meager set. We also discuss the weak difference property of ...
