                      calculations in conjunction with the frozen-magnon method,
                      we calculate exchange interactions, spin-wave dispersion,
                      and spin-wave stiffness constants in inverse-Heusler-based
                      spin gapless semiconductor (SGS) compounds Mn2CoAl, Ti2MnAl,
                      Cr2ZnSi, Ti2CoSi, and Ti2VAs. We find that their magnetic
                      behavior is similar to the half-metallic ferromagnetic
                      full-Heusler alloys, i.e., the intersublattice exchange
                      interactions play an essential role in the formation of the
                      magnetic ground state and in determining the Curie
                      temperature Tc. All compounds, except Ti2CoSi, possess a
                      ferrimagnetic ground state. Due to the finite energy gap in
                      one spin channel, the exchange interactions decay sharply
                      with the distance, and hence magnetism of these SGSs can be
                      described considering only nearest- and
                      next-nearest-neighbor exchange interactions. The calculated
                      spin-wave dispersion curves are typical for ferrimagnets and
                      ferromagnets. The spin-wave stiffness constants turn out to
                      be larger than those of the elementary 3d ferromagnets.
                      Calculated exchange parameters are used as input to
                      determine the temperature dependence of the magnetization
                      and Tc of the SGSs. We find that the Tc of all compounds is
                      much above the room temperature. The calculated
                      magnetization curve for Mn2CoAl as well as the Curie
                      temperature are in very good agreement with available
                      experimental data. This study is expected to pave the way
                      for a deeper understanding of the magnetic properties of the
                      inverse-Heusler-based SGSs and enhance the interest in these
                      materials for application in spintronic and
                      magnetoelectronic devices.},
