Abstract:
We provide a simple proof of Tchakaloff’s Theorem on the existence of cubature formulas of degree $m$ for Borel measures with moments up to order $m$. The result improves known results for non-compact support, since we do not need conditions on $(m+1)$st moments. In fact, we reduce the classical assertion of Tchakaloff’s Theorem to a well-known statement going back to F. Riesz.References
