Theory vs Cobordism - What's the difference?

theory | cobordism |

In context|mathematics|lang=en terms the difference between theory and cobordism

is that theory is (mathematics) a field of study attempting to exhaustively describe a particular class of constructs while cobordism is (mathematics) the theory and study of such objects.

As nouns the difference between theory and cobordism

is that theory is (obsolete) mental conception; reflection, consideration while cobordism is (mathematics) a connection between two manifolds of the same dimension (n) via a manifold of dimension n+1, where the smaller manifolds are included in the boundary of the larger manifold.

Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the ' theories .}}

  • A hypothesis or conjecture.
  • * 1999 , Wes DeMott, Vapors :
    • It's just a theory I have, and I wonder if women would agree. But don't men say a lot about themselves when a short-skirted woman slides out of a car or chair?
  • * 2003 , Sean Coughlan, The Guardian , 21 Jun 2003:
    • The theory is that by stripping costs to the bone, they are able to offer ludicrously low fares.
  • (countable, logic) A set of axioms together with all statements derivable from them. Equivalently, a formal language plus a set of axioms (from which can then be derived theorems).
    • A theory is consistent if it has a model.

    Usage notes

    In scientific discourse, the sense “unproven conjecture” is discouraged (with hypothesis or conjecture preferred), due to unintentional ambiguity and intentional equivocation with the sense “well-developed statement or structure”.
