Over last decade, various variant of stable maps modular space has been studied in connection to gauged linear sigma model. In this talk, we first propose the notion R-map to conceptualize these new modular space. The bulk of talk is to compactify these (open) moduli space by logarithmic R-map which carry two virtual fundamental cycles. Applications will be discussed. This is joint work with Qile Chen and Felix Janda.
