Sparse Moment Problems and Sparse Positivstellensätze from T-Systems
We give an introduction to T-systems. We arrive at the T-system Positivstellensatz of Karlin and show how we get the sparse Positivstellensätze on [a,b] and [0,∞). With these descriptions we show how to solve the 80 year old problem of the sparse Stieltjes moment problem and the more than 100 year old sparse Hausdorff moment problem.
