Query: Pulsation Modes of Long-Period Variables in the Period-Luminosity Plane   We present a phenomenological analysis of long-period variables (LPVs) in the
Large Magellanic Cloud with the aim of detecting pulsation modes associated to
different period-luminosity (PL) relations. Among brighter LPVs we discover a
group of triple-mode semiregular variables with the fundamental, first overtone
and second overtone modes simultaneously excited, which fall on PL sequences C,
C' and B, respectively. The mode identification in the fainter red giants is
more complicated. We demonstrate that the fundamental-mode pulsators partly
overlap with the first-overtone modes. We show a possible range of fundamental
mode and first overtone periods in the PL diagram.
