$ {\rm dom}({\rm ppl})=景觀
the domain of ppl is the landscape of string theory vacua;
$ {\rm im}({\rm ppl})
the image of ppl is the landscape of corresponding eQFTs that admit stringy UV-completion;
$ {\rm coker}({\rm ppl})=沼地
the cokernel of ppl is the swampland;
$ {\rm ker}({\rm ppl})
the kernel of ppl, or more generally its fiber over any EFT, is the space of different choices of stringy UV-completion of the same effective quantum field theory.
