May 20, 2015 at 3:03 comment added user61388 I know that in general this is a hard question, but in the cases of both Homogeneous quadratic forms and Frobenius-number types of problems there are techniques that can be used for large families of examples. I was curious if anyone knew of any such techniques here...
May 20, 2015 at 1:45 comment added Stanley Yao Xiao I am not sure what kind of answer you are looking for. In general one cannot expect a simple description for the set of numbers represented by a specific function. Are you looking for things like whether a given polynomial represents all numbers?
May 19, 2015 at 21:52 comment added user61388 Thanks, but what if I cannot do this? Are there other approaches for various families? Alternately, what if I wanted to limit solutions to integers greater than 2?
