We develop new computational tests for existence and uniqueness of representing measures μ in the Truncated Complex Moment Problem: (TCMP) γij ∫ z̄izj2 dμ (0 ≤ i + j ≤ 2n). We characterize the existence of finitely atomic representing measures in terms of positivity and extension properties of the moment matrix M(n)(γ) associated with γ ≡ γ(2n): γ00,. γ2n,0, γ00 0 (Theorem . ).

In this book, the authors develop new computational tests for existence and uniqueness of representing measures $mu$ in the Truncated Complex Moment Problem: $gamma _{ij}=int bar z^iz^j, dmu$ $(0le i+jle 2n)$.

Conditions for the existence of finitely atomic representing measures are expressed in terms of positivity and extension properties of the moment matrix $M(n)(gamma )$ associated with $gamma equiv gamma ^{(2n)}$: $gamma_{00}, dots ,gamma _{0,2n},dots ,gamma _{2n,0}$, $gamma _{00}>0$. This study includes new conditions for flat (i.e., rank-preserving) extensions $M(n+1)$ of $M(n)ge 0$; each such extension corresponds to a distinct rank $M(n)$-atomic representing measure, and each such measure is minimal among representing measures in terms of the cardinality of its support. For a natural class of moment matrices satisfying the tests of recursive generation, recursive consistency, and normal consistency, the existence problem for minimal representing measures is reduced to the solubility of small systems of multivariable algebraic equations. In a variety of applications, including cases of the quartic moment problem ($n=2$), the text includes explicit contructions of minimal representing measures via the theory of flat extensions. Additional computational texts are used to prove non-existence of representing measures or the non-existence of minimal representing measures. These tests are used to illustrate, in very concrete terms, new phenomena, associated with higher-dimensional moment problems that do not appear in the classical one-dimensional moment problem.
