On a construction method of new moment sequences
Seunghwan Baek, Hayoung Choi, Seonguk Yoo
In this paper we provide a way to construct new moment sequences from a given moment sequence. An operator based on multivariate positive polynomials is applied to get the new mome…
Any multi-index sequence has an interpolating measure
Hayoung Choi, Seonguk Yoo
R. P. Boas showed that any single-index sequence of real numbers can be represented as (), where…
Catalan-like numbers and Hausdorff moment sequences
Hayoung Choi, Yeong-Nan Yeh, Seonguk Yoo
In this paper we show that many well-known counting coefficients, including the Catalan numbers, the Motzkin numbers, the central binomial coefficients, the central Delannoy number…
A new approach to the nonsingular cubic binary moment problem
Raul E. Curto, Seonguk Yoo
We present an alternative solution to nonsingular cubic moment problems, using techniques that are expected to be useful for higher-degree truncated moment problems. In particular,…
Non-extremal sextic moment problems
Raul E. Curto, Seonguk Yoo
Positive semidefiniteness, recursiveness, and the variety condition of a moment matrix are necessary and sufficient conditions to solve the quadratic and quartic moment problems. A…
The Division Algorithm in Sextic Truncated Moment Problems
Raul E. Curto, Seonguk Yoo
For a degree 2n finite sequence of real numbers to have a representing meas…
Concrete Solution to the Nonsingular Quartic Binary Moment Problem
Raul E. Curto, Seonguk Yoo
Given real numbers , , , , , , , , , , , , $β_{2…
Cubic column relations in truncated moment problems
Raul E. Curto, Seonguk Yoo
For the truncated moment problem associated to a complex sequence to have a representing measure , it is necessary for the momen…
