| Abstract: | We demonstrate that Martin's axiom for  -centered notions of forcing implies the existence of a van der Waerden space that is not a Hindman space. Our proof is an adaptation of the one given by M. Kojman and S. Shelah that such a space exists if one assumes the continuum hypothesis to be true. |
| Keywords: | General topology continuum hypothesis Martin's axiom van der Waerden space Hindman space arithmetic sequence convergent sequence |
