Concluding remarks

We cannot presume to summarize all of the science we've discussed in the talks, posters, and informal discussions. Here, we discuss a few of the themes that emerged, concentrating on the theoretical basis that Wojtek Dziembowiski and his colleagues have developed and explored over the past 40+ years. We connect those with observational results - especially those from recent ground-based surveys and space-based missions that have revolutionized the study of stellar variability.
