    A harmonic-type maximal principle in the three chains completion problem (2000)
    Springer
    Integral equations and operator theory 36 (2000), S. 396-408

    ISSN: 1420-8989

    Topics: Mathematics
    Notes: Abstract In this note, we prove a harmonic-type maximal principle for the Schur parametrization of all contractive interpolants in the three chains completion problem (see [4]), which is analogous to the maximal principle proven in [2] in case of the Schur parametrization of all contractive intertwining liftings in the commutant lifting theorem.

    Evolution of Dynamical Coupling in Scalar Tensor Theory from Noether Symmetry (2000)
    Springer
    General relativity and gravitation 32 (2000), S. 1615-1626 
    Details
    ISSN: 1572-9532
    Keywords: Brans–Dicke theory ; cosmology
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We present the gravitational coupling function ω(φ) in the vacuum scalar-tensor theory as allowed by the Noether symmetry. We also obtain some exact cosmological solutions in the spatially homogeneous and isotropic background thereby showing that the attractor mechanism is not effective enough to reduce the theory to Einstein theory. It is observed that, asymptotically, the scalar tensor theory goes over to Einstein theory with a finite value of ω. This work thus supports earlier works in this direction.
