This book focuses on the stellar disk evolution and gas disk
turbulence of the most numerous galaxies in the local Universe -
the dwarf galaxies. The "outside-in" disk shrinking mode was
established for a relatively large sample of dwarf galaxies for the
first time, and this is in contrast to the "inside-out" disk growth
mode found for spiral galaxies. Double exponential brightness
profiles also correspond to double exponential stellar mass
profiles for dwarf galaxies, which is again different from most
spiral galaxies. The cool gas distribution in dwarf galaxies was
probed with the spatial power spectra of hydrogen iodide (HI) gas
emission, and provided indirect evidence that inner disks of dwarf
galaxies have proportionally more cool gas than outer disks. The
finding that no correlation exists between gas power spectral
indices and star formation gave important constraints on the
relation between turbulence and star formation in dwarf galaxies.
