Abstract We investigate the strong gravitational lensing phenomena caused by a black hole with dark matter halo in presence of cloud string and quintessence. This study examines two significant models: universal rotation curve model cold model. To do this, we first numerically estimate coefficients deflection angles for both models. It is observed that angle, denoted as $$\alpha _D$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>α</mml:mi> <mml:mi>D</mml:mi>...
