Abstract

Let k,aNk,a\in \mathbb{N} and let p1,,pkQ[n]p_1,\cdots,p_k\in \mathbb{Q}[n] with zero constant term. We show that for any finite coloring of Q\mathbb{Q}, there are non-zero x,yQx,y\in \mathbb{Q} such that there exists a color which contains a set of the form {x,xya,x+p1(y),,x+pk(y)}\Big\{x,\frac{x}{y^a},x+p_{1}(y),\cdots,x+p_{k}(y)\Big\} and there are non-zero v,uQv,u\in \mathbb{Q} such that there exists a color which contains a set of the form {v,vua,v+p1(u),,v+pk(u)}.\Big\{v,v\cdot {u^a},v+p_{1}(u),\cdots,v+p_{k}(u)\Big\}.
