The treewidth of a graph G is the minimum width over all possible tree decompositions of G, and it is written as tw (G).
The opposite of the bottom-up paradigm is the top-down paradigm, based on steps of decomposition and generalization.
The number [tau] = n + m for n and m in the previous definition is called the Tarski number of that paradoxical decomposition; the minimum of all such numbers over all the possible paradoxical decompositions of G, is called the Tarski number of G and denoted by [tau](G).

1999) presented the solution for mixed Volterra-Fredholm integral equation by using Adomian decompositions method and the reliable treatment for solving mixed Volterra-Fredholm integral equation by using modified decomposition method was given by Wazwaz (See Wazwaz, 2002).
Intended for non-experts, this begins with background material on the relevant constructions from algebraic topology and on local geometries from group theory, reviewing aspects of group cohomology, simplicial sets and their equivalence with topological space, Bousfield-Kan completions and homotopy colimits, decompositions and p-subgroups, and 2-local geometries for simple groups.
Decompositions does not shy from morbid topics in classic writings, such as the deathless apparition in Maurice Blanchot's "Death Sentence", Poe's frightening account of hypnotic suspension, and Rene Daumal's dangerous experiments with asphyxiation.
One set of regression estimates is sufficient to resolve the identification problem in the detailed decompositions.
Hence, these generalized decompositions are invariant to the ordering of variables in a VAR.

2) After BEMD, when the two images to be obtained from the fusion component do not have the same number of BIMFs, the adjacent BIMF component must be reconstructed into a new component m-BIMF, and the common number n must be set, so as to stabilize the two decompositions of the images into a BIMF.
