prodded by discussion here I finally gave this an entry, explaining what I propose is the right slogan:

swampland = cokernel of point-particle-limit-map

added an improved graphics for that statement: Swampland = Cokernel

Are there names for $image(ch \cdot \beta)$ and $cokernel(ch \cdot \beta)$?

You might call image and cokernel of the composite maps, all the way from M-theory, through string theory, to effective field theory, the “real non-perturbatively corrected” Landscape and Swampland.

As you know, Tom Banks’ recent rant was all about how that “real non-perturbaitive” Landscape/Swampland should be entirely different from the naive EFT picture of the Landscape/Swampland (corresponding here to image/cokernel of just $ch$ itself). But I don’t recall that he used any particularly catchy phrase for the distinction.
