TITLE: On the mass-transfer problem in symbiotic binaries AUTHOR: A. Skopal ABSTRACT: My contribution is focused to the principal interaction between the binary components of symbiotic stars - the mass transfer via the wind. I will introduce the way how to estimate the mas-loss rate from the giant, and point the long-standing problem given by the high luminosity of the white dwarf accretor and its deficient fueling by the cool giant donor. I will suggest possible solution of the problem by a wind compression towards the orbital plane.
