Correction: Halun et al. Investigation of Ring and Star Polymers in Confined Geometries: Theory and Simulations. Entropy 2021, 23, 242

The authors wish to make the following correction to this paper [1]. In our paper [1] are a few errors:

1. On page 8 symbol ‘$cc$’ before $<{\rho }_{\lambda }^{\left(DD\right)}\left(\tilde{z}\right)>$ in the Equation (19) should be removed and looks like:

   $$\begin{array}{cc}\hfill <{\rho }_{\lambda }^{\left(DD\right)}\left(\tilde{z}\right)>& =\frac{{\left(2R_g\right)}^{1/\nu }}{L_0}\frac{\mathcal{IL}{\int }_0^{L}dzG(;z,\tilde{z})G(;\tilde{z},z)}{\mathcal{IL}{\int }_0^{L}dzG(;z,z)}\hfill \\ \hfill & \approx 2\frac{{\tilde{z}}^{1/\nu }}{L}(1+\frac{\sqrt{\pi }}{2y}+\frac{\pi }{4y^2}+\frac{{\pi }^{3/2}}{8y^3}+O\left(e^{-4y^2}\right))\hfill \end{array}$$ (19)
2. On page 12 symbol ‘$cc$’ before $<{\rho }_{\lambda }^{\left(DD\right)}\left(\tilde{z}\right){>}_l$ in the Equation (25) should be removed and looks like:

   $$\begin{array}{cc}\hfill <{\rho }_{\lambda }^{\left(DD\right)}\left(\tilde{z}\right){>}_l=B\frac{{\tilde{z}}^{1/\nu }}{L}(1& +8a\pi \tilde{R}([erfc\left[\frac{a}{\sqrt{2}{R}_x}\right]-\frac{R_x}{a}\sqrt{\frac{2}{\pi }}{e}^{-\frac{a^2}{2R_x^2}}]\hfill \\ \hfill & -2[erfc\left[\frac{\sqrt{2}a}{R_x}\right]-\frac{R_x}{a\sqrt{2\pi }}{e}^{\frac{-2a^2}{R_x^2}}]\left)\right)\hfill \end{array}$$ (25)
3. On page 16 symbol ‘$cc$’ before $<{\rho }_{\lambda }^{\left(DD\right)}\left(\tilde{z}\right){>}_{st}$ in the Equation (44) should be removed and looks like:

   $$\begin{array}{cc}\hfill <{\rho }_{\lambda }^{\left(DD\right)}(\tilde{z}){>}_{st}=B\frac{{\tilde{z}}^{1/\nu }}{L}(1& -2\sqrt{5\pi }\tilde{R}a[(\frac{61R_x}{7a}+\frac{1584}{175}\frac{a}{R_x})e^{-\frac{4a^2}{5R_x^2}}\hfill \\ & -(\frac{155R_x}{7a}+\frac{\mathrm{10,272}}{175}\frac{a}{R_x})e^{-\frac{16a^2}{5R_x^2}}])\hfill \end{array}$$ (44)
4. On page 21 Appendix B symbol ‘$ccccc$’ before ${\tilde{G}}_{\Vert }(\mathbf{p};z,z^{\prime };{\mu }_0,c_{1_0},c_{2_0},L)$ in the Equation (A5) should be removed and looks like:

   $$\begin{array}{cc}\hfill {\tilde{G}}_{\Vert }(\mathbf{p};z,z^{\prime };{\mu }_0,c_{1_0},c_{2_0},L)& =\frac{1}{2{\kappa }_0}(({\kappa }_0^2+{\kappa }_0(c_{1_0}+c_{2_0})+c_{1_0}{c}_{2_0})e^{{\kappa }_{0}L}\hfill \\ \hfill & -({\kappa }_0^2-{\kappa }_0(c_{1_0}+c_{2_0})+c_{1_0}{c}_{2_0})e^{-{\kappa }_{0}L}{)}^{-1}\hfill \\ \hfill & (({\kappa }_0^2+{\kappa }_0(c_{1_0}+c_{2_0})+c_{1_0}{c}_{2_0})e^{{\kappa }_0(L-|z-z^{\prime }|)}\hfill \\ \hfill & +({\kappa }_0^2-{\kappa }_0(c_{1_0}+c_{2_0})+c_{1_0}{c}_{2_0})e^{-{\kappa }_0(L-|z-z^{\prime }|)}\hfill \\ \hfill & +({\kappa }_0^2+{\kappa }_0(c_{2_0}-c_{1_0})-c_{1_0}{c}_{2_0})e^{{\kappa }_0(L-z-z^{\prime })}\hfill \\ \hfill & +({\kappa }_0^2-{\kappa }_0(c_{2_0}-c_{1_0})-c_{1_0}{c}_{2_0})e^{-{\kappa }_0(L-z-z^{\prime })})\hfill \end{array}$$ (A5)
5. On page 22 Appendix C symbol ‘$cc$’ before $<{\rho }_{\lambda }^{(DN)}(\tilde{z})>$ in the Equation (A8) should be removed and looks like:

   $$\begin{array}{cc}\hfill <{\rho }_{\lambda }^{(DN)}(\tilde{z})>& =\frac{{(2R_g)}^{1/\nu }}{L_0}\frac{\mathcal{IL}{\int }_0^{L}dzG(;z,\tilde{z})G(;\tilde{z},z)}{\mathcal{IL}{\int }_0^{L}dzG(;z,z)}\hfill \\ \hfill & \approx 2\frac{{\tilde{z}}^{1/\nu }}{L}+\frac{\tilde{z}}{y^2}\frac{(e^{-4y^2}-e^{-16y^2})}{(1-2e^{-4y^2}+2e^{-16y^2})}\hfill \end{array}$$ (A8)
