Abstract
The problem of completing a partially prescribed Toeplitz matrix to a posit ive definite Toeplitz matrix is considered. The main result is a characteri zation of the patterns of specified entries that guarantee the existence of a positive definite Toeplitz completion of a partial positive definite Toe plitz matrix. This characterization resolves affirmatively a conjecture of C. R. Johnson and L. Rodman.
