logic: unification of a formula - Mathematics Stack Exchange The Unification Algorithm is described at page 84 You have to recall the resolution calculus [page 29] : Resolution is a simple syntactic transformation applied to formulas From two given formulas in a resolution step (provided resolution is applicable to the formulas), a third formula is generated
Unification of an expression - Mathematics Stack Exchange Unification is not possible for these expressions I wanna know if this Unification failure isn't only due to the chosen Substitution ? For example why they didn't substitute: X f(a) and then X g(y) to get p(X,X) and p(X,X) ?
What is How to do Unification - Mathematics Stack Exchange In a now deleted answer, sunflower gave a unification algorithm which has an explicit rule to that effect: "The unification of two functors with different name or arity fails " From your comment under the question it seems you have access to textbooks with unification algorithms
The Langlands program for beginners - Mathematics Stack Exchange $\begingroup$ @ABC, Langlands isn't really a grand unified theory of mathematics - that's just something Edward Frenkel said to convey the importance of the work to convey the importance of the program to the interested non-expert
Is there a unified description of the geometric derivative? The geometric derivative seems like it should offer further unification, because, at least for vectors, it combines the interior and exterior derivatives into one But the question is, how can I describe the meaning of the geometric derivative without resorting to describing each component separately?
group theory - What is the algebraic intuition behind Vieta jumping in . . . If you wish to develop a deeper understanding of these proofs then I highly recommend that you study them from this more general perspective, where you will find much beauty and unification The group laws on conics can be viewed essentially as special cases of the group law on elliptic curves (e g see Franz Lemmermeyer's "poor man's" papers
Why should faithfully flat descent preserve so many properties? I think that a "faithfully flat" morphism in algebraic geometry can be thought of as analogous to a surjective map of sets (maybe more accurately as something like a fibration with surjective image)
