N2 - We perform the first amplitude analysis of 퐷+푠→휋+휋+휋−휋0 decays based on data samples of electron-positron collisions recorded with the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of 7.33 fb−1. We report the observation of 퐷+푠→푓0(980)휌(770)+ with a statistical significance greater than 10휎 and determine the branching fractions ℬ(퐷+푠→휋+휋+휋−휋0|non−휂)=(2.04±0.08stat±0.05syst)% and ℬ(퐷+푠→휂휋+)=(1.56±0.09stat±0.04syst)%. Moreover, we measure the relative branching fraction between 휙→휋+휋−휋0 and 휙→퐾+퐾− to be [ℬ(휙(1020)→휋+휋−휋0)/ℬ(휙(1020)→퐾+퐾−)]=0.230±0.014stat±0.010syst., which deviates from the world average value by more than 4휎.
