A rigorous theoretical investigation has been made of obliquely propagating electrostatic solitary structures in a hot magnetized dusty plasma which consists of a negatively charged, extremely massive, hot, dust Ñuid and Maxwellian distributed ions and electrons. The reductive perturbation method has been employed to derive the KortewegÈde Vries (KÈdV) equation which admits a solitary wave solution for small but Ðnite amplitude limit. It has been shown that the e †ects of dust-temperature, obliqueness, magnetic Ðeld and free electrons have changed the nature of the electrostatic solitary structures. The result of the present investigation for unmagnetized case, parallel propagation, no free electron and cold dust Ñuid completely agrees with the existing published results (Mamun et al. [4]).
