Besides, we define the concept of slow oscillation with respect to logarithmic summability in $IFNS$, investigate its relation with the concept of q-boundedness and give Tauberian theorems by means of q-boundedness and slow oscillation with respect to logarithmic summability. A comparison theorem between Ces`{a}ro summability method and logarithmic summability method in $IFNS$ is also proved in the paper.engAraştırma Makalesi10.33401/fujma.792994
