partial algebra

In abstract algebra, a partial algebra is a generalization of universal algebra to partial operations.{{cite book|editor1=Ivo G.

Example(s)

  • partial groupoid
  • field — the multiplicative inversion is the only proper partial operation
  • effect algebras{{Cite journal | doi = 10.1007/BF02283036| title = Effect algebras and unsharp quantum logics| journal = Foundations of Physics| volume = 24| issue = 10| pages = 1331| year = 1994| last1 = Foulis | first1 = D.

Structure

There is a "Meta Birkhoff Theorem" by Andreka, Nemeti and Sain (1982).
