To study the sign problem, we propose a mini-max characterization of the coefficients in the reaction terms when the wave speed is zero. Applying our characterization, some explicit conditions under which the speed sign can be determined are obtained.competition-diffusion | Lotka-Volterra | traveling wave[SDGs]SDG3journal article10.3934/dcdsb.20230522-s2.0-85167686110https://api.elsevier.com/content/abstract/scopus_id/85167686110
