The choice of abbreviation "TF" and "TN" in EGA II

73 Views Asked by At

I am a native French speaker, yet I cannot guess what the abbreviations "TF" and "TN" stand for in page 39 (where they define them). I assume that the F stands for some kind of Finite and N for some kind of Nul, but I can't figure out the T. Does anyone know? That would be a really fun fact to know.
