    "abstract": "A non-isospectral (2+1) dimensional integrable spin equation is investigated.\nIt is shown that its geometrical and gauge equivalent counterparts is the (2+1)\ndimensional nonlinear Schr\\\"odinger equation introduced by Zakharov and studied\nrecently by Strachan. Using a Hirota bilinearised form, line and curved soliton\nsolutions are obtained. Using certain freedom (arbitrariness) in the solutions\nof the bilinearised equation, exponentially localized dromion-like solutions\nfor the potential is found. Also, breaking soliton solutions (for the spin\nvariables) of the shock wave type and algebraically localized nature are\nconstructed.",
