  "abstract": "We extend the global existence results for critical parameters of [Bianchini and Leccese, J. Math. Anal. Appl. (2024)] to the multidimensional problem \\begin{equation*} \\partial_t u + \\text{div } (b(t,x) u^{1+k}) = Δu \\end{equation*} for $b:\\mathbb R\\times{\\mathbb R}^d\\to{\\mathbb R}^d$ non-autonomous fields, in the case \\begin{equation*} (\\text{div } b)_-\\in L^\\infty_{\\mathrm{loc}} \\big([0,\\infty);L^{p,\\infty}({\\mathbb R}^d)\\big), \\qquad p>d. \\end{equation*} The proof of global existence follows the parabolic symmetrization approach of [Bandle, J. Analyse Math. (1976)] and is based on the study of the function \\begin{equation*} m(t,s)=\\int_0^s u^*(t,r)\\,dr. \\end{equation*}",
