Query: Gamma-rays as a diagnostic of the origin of core radiation in
  low-luminosity active galactic nuclei   The respective contribution of disk and jet components to the total emission
in low luminosity active galactic nuclei (LLAGNs) is an open question. This
paper suggests that $\gamma$-rays emitted from electrons accelerated in jets
could be a direct diagnostic tool for a jet component to the total emission. We
demonstrate $\gamma$-ray flux from jets based on a synchrotron self-compton
(SSC) model on the assumption that radio and X-rays are dominantly produced
from jets in the case of a high state of a nearby LLAGN, NGC 4278. We also
survey parameter space in the model. Observational properties of LLAGNs in
radio and X-ray bands allow to constrain physical parameters in an emission
region. The size of the emission region $R$ is limited to $10^{16}$ cm $\leq R
\leq 10^{17.5}$ cm if the observed tight correlation between radio and X-ray
emission originates from the same jet component. If the beaming factor of the
emission region is close to the observed parsec scale jet of NGC 4278 and $R
\sim 10^{16}$ cm, the $\gamma$-rays may be detected by Cherenkov Telescope
Array, and the jet domination can be tested in the near future.
