 Abstract: We consider the following system of equations $$\begin{array}{c} {\rm div}\, (\varrho \mathbf{u}) = 0,\ {\rm div}\, (\varrho \mathbf{u} \otimes \mathbf{u}) - {\rm div} {\mathbf{S}}+ \nabla {\pi} =\varrho\mathbf{f},\ {\rm div}\, (\varrho E \mathbf{u}) + {\rm div}\, (\mathbf {Q}+\pi\mathbf{u} -\mathbf{S}\mathbf{u})= \varrho\mathbf{f}\cdot \mathbf{u},\ {\rm div}\, (\varrho Y_k \mathbf{u})+ {\rm div}\, \mathbf {F}_k = m_k\omega_{k},\quad k=1,\dots, L \end{array}$$ which describes the steady flow of a compressible heat conducting mixture of gases whose component may chemically react, where only the barycentric velocity is taken into account. We consider either the no-slip or the Navier boundary conditions for the velocity and the Newton boundary condition for the temperature. Based on papers [1]--[3] we present existence results of weak and variational entropy solutions in different situations. \[5mm] {\bf References} \[2mm] [1] Giovangigli, V., Pokorn\y, M., Zatorska, E.: \emph{On the steady flow of reactive gaseous mixture}, Analysis (Berlin) 35, no. 4, 319--341 (2015). \[1mm] [2] Piasecki, T., Pokorn\y, M.: \emph{Weak and variational entropy solutions to the system describing steady flow of a compressible reactive mixture}, Nonlinear Anal.
