Is the tag algebraic-cobordism useful? I am asking because it is currently used on a single question. Tags which have only a single occurrence and empty tag-wiki are removed by an automated process after 6 months.

@MartinSleziak Dunno if it is an appropriate tag, but it is certainly a legitimate math topic, and there are other questions that could be tagged with it (for example https://mathoverflow.net/questions/235033/is-mgl-an-h-mathbbz-algebra , https://mathoverflow.net/questions/283311/c-2-equivariant-betti-realization-of-mgl and https://mathoverflow.net/questions/111849/the-vanishing-of-mgl2ni-nx-do-spectra-of-smooth-projective-varieties-ge), although they tend to have already enough tags
