	Order-embedding - Wikipedia, the free encyclopedia
		In mathematical order theory, an order-embedding is a special kind of monotone function, which provides a way to include one partially ordered set into another.
		An order isomorphism can be characterized as a surjective order-embedding.
		Formally, given two partially ordered sets (S, ≤) and (T, <=), a function f: S → T is an order-embedding if f is both order-preserving and order-reflecting, i.e.

		A total order of the tokens of all the signals of the process would cause an overspecification of the system.

	The Thrackle Problem
		According to the order and the orientation with which the fourth line crosses the first and second line, the embeddings are classified (by us) as zero, plus or minus.
		A C-program generated all thrackle embeddings of cycles of order 6 - 10 and analyzed which sequences of configurations occur.
		If a cycle of order N has a thrackle embedding, then so does the cycle of order N+2.

	spatial-esop05.txt
		I believe that the ability of embedding 2nd order logic in spatial logic is very surprising and if the results holds the paper should be definitely accepted.
		But now we must ask whether the other embedding, that of a specific instance of first-order-logic-with-* into second-order logic, is as significant as the paper's title claims.
		-The embedding of 2nd order logic in this logic is surprising and non-obvious.

	First-order Model Theory
		The elements of C are the ordered pairs (a,b) where a is an element of A and b is an element of B.
		Then there are an elementary extension D of B and an elementary embedding e of C into D such that (i) for each element a of A, e(a) = a, and (ii) if c is an element of C but not of A, then e(c) is not in B.
		We say that e is an elementary embedding of A into B if e is an elementary map and its domain is the whole domain of A.

		Most of the available documentation on extending and embedding perl is written from the prospective of the core perl developers for core perl developers.
		Extending and Embedding Perl is as it boldly states on the cover: "The definitive guide to XS, embedding, and the Perl internals".
		It does an excellent job of explaining the hairy details of working with Perl at the C level, whether etending Perl (the bulk of this book), embedding it in other apps, or hacking the guts.

	Groups with Word Problem in NP, and Higman Embeddings
		The well known Higman embedding theorem says that a group has a recursive presentation if and only if this group is embeddable into a finitely presented group.
		In the case when the initial group might have torsion, the solvability of the order problem is essential because it is easy to costruct a finitely generated group with solvable power problem but unsolvable order problem, which is not embeddable into any group with solvable conjugacy problem (hint: conjugated elements must have the same order).
		It is easy to see using Magnus' embedding that for every normal subgroup N of a free finitely generated group F if F / N has word problem in NP (resp.

	Citebase - On Spatial Conjunction as Second-Order Logic
		These embeddings show that the satisfiability of formulas in first-order logic with spatial conjunction is equivalent to the satisfiability of formulas in second-order logic.
		The embedding into spatial conjunction also has useful consequences: because a restricted form of spatial conjunction in two-variable logic preserves decidability, we obtain that a correspondingly restricted form of second-order quantification in two-variable logic is decidable.
		We construct an embedding from first-order logic with spatial conjunction into second-order logic, and more surprisingly, an embedding from full second order logic into first-order logic with spatial conjunction.

	Introduction to the IFF-ONT
		A concept lattice consists of: a collection of instances, a collection of types, a collection of formal concepts, an embedding map from instances to concepts, an embedding map from types to concepts, an order relation on concepts, and meet and join operators that map subcollections of concepts to single concepts.
		Each first order type language L has an associated truth classification, whose collection of instances mod(L) is the class of models of the language, whose collection of types expr(L) is the set of expressions of the language, and whose incidence is satisfaction.
		Lattice order is reverse subset inclusion on the theorem sets of closed theories.

	ORDINAL REAL NUMBERS 2
		universal embedding property for the category of linearly ordered fields, that is every linearly ordered field has an monomorphic image in some field of the hierarchy.The hierarchy of transfinite real numbers is known to have, also, this property.Such hierarchies we call universal embedding hierarchies.
		It is surprising that in one of the consequences of the theory of ordinal real numbers, it is proved a far more advanced and complete result for the whole category of order types that has as corollary the previous important and elementary arithmetisation.
		Although more advanced, the result remains in the context of elementary theory of ordinal real numbers.In this result any order type can be “discretised” or “arithmetised” through the ordinal numbers.

	Extending Models of Second Order Predicate Logic to Models of Second Order Dependent Type Theory (ResearchIndex)
		Apart from the construction being of interest by itself, this also suggests a way of proving the completeness of the formulasas -types embedding from second order predicate logic to second order dependent type theory.
		We describe a method for constructing a model of second order dependent type theory out of a model of classical second order predicate logic.
		Under this embedding, formulas are interpreted as types, and derivability (of a formaula) in the logic should correspond to inhabitation...

	Abstracts of papers by Peter J. Cameron
		After an introduction to first-order logic and a discussion of which graph properties are first-order, we consider various logical concepts such as aleph_0-categoricity and homogeneity for graphs, and present a couple of theorems about finite graphs requiring logical techniques in their proofs.
		An early result on this is Greene's theorem asserting that the weight enumerator of the code is a specialisation of the Tutte polynomial of the matroid.
		Observing that the cycle index is the probability generating function for cycle structure, we recover the earlier theorem, as well as a recent result of Parker.

	Extending Vs. Embedding
		Embedding is inserting calls into your C or C++ application after it has started up in order to initialize the Python interpreter and call back to Python code at specific times.
		Your developers are already probably angry at you for embedding, given that they can't use the other libraries and applications they're used to having at their disposal in Python.
		As I said, you can use embedding as a stopgap measure, but it is no substitute for clean code.
