abstract = {Context. 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.Aims. By modeling the
spectral energy distributions of PKS 0735+178, we aimed to
explore the physical conditions that lead to neutrino
production at different stages of the source's
activity.Methods. We analyzed the multiwavelength data from
the selected time periods. Using numerical simulations of
radiation processes in the source, we explored the parameter
space of one-zone leptonic and leptohadronic models to find
the best-fit solutions that explain the observed photon
fluxes.Results. We demonstrated how model parameter
degeneracy affected the prediction of neutrino spectra. We
showed that the available multiwavelength data were
insufficient to predict the neutrino spectrum unambiguously.
However, under the condition of neutrino rates maximization,
we proposed a scenario in which 0.1 neutrino events were
produced during the 50-day flare.Key words: neutrinos /
