Correction to: Unsteady Convective MHD Flow and Heat Transfer of a Viscous Nanofluid across a Porous Stretching/Shrinking Surface: Existence of Multiple Solutions (Crystals, (2021), 11, 11, (1359), 10.3390/cryst11111359)

We ought to correct the misprinted terms in our published paper ‘Unsteady Convective MHD Flow and Heat Transfer of a Viscous Nanofluid across a Porous Stretching/Shrinking Surface: Existence of Multiple Solutions’ [Crystals 2021, 11, 1359]. All the important outcomes of the published paper are correct, apart from the two existing misprints. As a result of these errata, we have introduced the right terms. The sentence, “which are assumed to be varying from a stagnation point, respectively, represented by (Formula presented.) and (Formula presented.). where a, b and δ are positive constant. The dimension of a and b is t⁻¹…”, in line 9–10 of the section Mathematical Modelling of Ref. [1], should be replaced with “are assumed to be represented by (Formula presented.) and (Formula presented.) respectively, where a is positive constant. The dimension of a is t⁻¹…”. The fourth boundary condition (Formula presented.) in Equation (12) of Ref. [1] should be replaced with (Formula presented.).
