  ABSTRACT: The study derives the Hirota bilinear form for a variable-coefficient (2 + 1)-dimensional BKP equation and constructs N-soliton, M-lump, and mixed lump-soliton solutions. By testing four representative time-dependent coefficient sets, the authors visualise how α( t ) , β( t ) and δ( t ) shape the spatial patterns of solitons and lumps. The work emphasises the richer structural diversity and evolution pathways that arise when coefficients vary with time.
