Journal of Physical Studies 6(1), 124–132 (2002) DOI: https://doi.org/10.30970/jps.06.124 INTEGRAL-FUNCTIONAL REPRESENTATION OF MASS OPERATOR OF QUASIPARTICLES INTERACTING WITH POLARIZATIONAL PHONONS AT T = 0 К М. V. Tkach Chernivtsi National University, Department of Theoretical Physics, 2 Kotsubinsky Str., 274012, Chernivtsi, Ukraine

The integral-functional representation of mass operator of spinless quasiparticles interacting with polarizational phonons at $T=0$ K is obtained for the first time. This representation is equivalent to the infinite branched integral fraction. It does not depend on the binding force and effectively takes into account the many phonon processes.
