  To investigate the excitation of kink oscillations in coronal loops and
filaments, a C3.4 circular-ribbon flare (CRF) associated with a blowout jet in
active region 12434 on 2015 October 16 is analyzed. The flare excited
small-amplitude kink oscillation of a remote coronal loop. The oscillation
lasted for $\ge$4 cycles without significant damping. The amplitude and period
are 0.3$\pm$0.1 Mm and 207$\pm$12 s. Interestingly, the flare also excited
transverse oscillation of a remote filament. The oscillation lasted for
$\sim$3.5 cycles with decaying amplitudes. The initial amplitude is 1.7$-$2.2
Mm. The period and damping time are 437$-$475 s and 1142$-$1600 s. The starting
times of simultaneous oscillations of coronal loop and filament were concurrent
with the hard X-ray peak time. Though small in size and short in lifetime, the
flare set off a chain reaction. It generated a bright secondary flare ribbon
(SFR) in the chromosphere, remote brightening (RB) that was cospatial with the
filament, and intermittent, jet-like flow propagating in the northeast
direction. The loop oscillation is most probably excited by the flare-induced
blast wave at a speed of $\ge$1300 km s$^{-1}$. The excitation of the filament
oscillation is more complicated. The blast wave triggers secondary magnetic
reconnection far from the main flare, which not only heats the local plasma to
higher temperatures (SFR and RB), but produces jet-like flow (i.e.,
reconnection outflow) as well. The filament is disturbed by the secondary
magnetic reconnection and experiences transverse oscillation. The findings give
new insight into the excitation of transverse oscillations of coronal loops and
filaments.
