For this example, yo can do Apply[And, (x[#] >= 0) & /@ Range[5]] For example, Assuming[(x[#] >= 0) & /@ Range[5], Simplify[Sqrt[x[2]^2]]] On the other hand, AFAIK patterns do not work in this situation. > Dear All, > > > > How can one formulate the set of constraints > > > > x[1] >= 0, x[1] >= 0, x[2] >= 0, x[3] >= 0, x[4] >= 0, x[5] >= 0 > > > > by using a compact form? > > > > Thanks in advance, > > > > Paul
