The Tantawy technique for modeling fractional KdV and mKdV positron-acoustic solitary waves in an electron-positron-ion plasma with regularized $$\kappa -$$ distribution

Abstract This work investigates the dynamical behavior of both the integer and fractional-order positron-acoustic solitary waves (PASWs) in a collisionless, unmagnetized electron-positron-ion plasma composed of stationary positive ions, inertial cold positrons, inertialess hot Maxwellian positrons,...
