The deep inelastic scattering mode of ##IMG## [http://ej.iop.org/images/0295-5075/130/5/51002/epl20182ieqn1.gif] {$t\overline{t}$} pair production at the proposed LHeC and FCC-eh is considered. We present a method to extract the top reduced cross-section related to the transversal structure function F 2 ( x , Q 2 ) parameterization. Numerical calculations with known kinematics of the LHeC and FCC-eh colliders are presented. The results obtained for charm and beauty pair production are comparable with the experimental data. We show that for a wide range of the momentum transfer into the top quark pair, the reduced cross-section is well described by center-of-mass energies.
