      abstract     = {The origin of the astrophysical neutrino flux discovered by
                      IceCube remains largely unknown. Several individual neutrino
                      source candidates were observed. Among them is the gamma-ray
                      flaring blazar TXS 0506+056. A similar coincidence of a
                      high-energy neutrino and a gamma-ray flare was found in
                      blazar PKS 0735+178. By modeling the spectral energy
                      distributions of PKS 0735+178, we expect to investigate the
                      physical conditions for neutrino production during different
                      stages of the source activity. We analyze the
                      multi-wavelength data during the selected periods of time.
                      Using numerical simulations of radiation processes in the
                      source, we study the parameter space of one-zone leptonic
                      and leptohadronic models and find the best-fit solutions
                      that explain the observed photon fluxes. We show the impact
                      of model parameter degeneracy on the prediction of the
                      neutrino spectra. We show that the available
                      mutli-wavelength data are not sufficient to predict the
                      neutrino spectrum unambiguously. Still, under the condition
                      of maximal neutrino flux, we propose a scenario in which 0.2
                      neutrino events are produced during the 50 days flare.},
