In the matroid theory of graphs the rank of an undirected graph is defined as the number n − c, where c is the number of connected components of the graph. [1] Equivalently, the rank of a graph is the rank of the oriented incidence matrix associated with the graph. [2] Analogously, the nullity of the graph is the nullity of its oriented ...
One of its amendments provided that, a federal reserve bank may discount any commercial, agricultural or industrial paper for liquidity purposes. It also allowed necessary advances to its member banks secured by "any sound asset" [2] that would otherwise be described as ineligible [2] by the orthodox theory to provide bank reserves.

Frost Bank is an American bank based in San Antonio that is chartered in Texas, with 155 branches and 1,700 automated teller machines in the state. It is the primary subsidiary of Cullen/Frost Bankers, Inc., a bank holding company.
Spectral graph theory is the branch of graph theory that uses spectra to analyze graphs. See also spectral expansion. split 1. A split graph is a graph whose vertices can be partitioned into a clique and an independent set. A related class of graphs, the double split graphs, are used in the proof of the strong perfect graph theorem.
The "pearls" of the title include theorems, proofs, problems, and examples in graph theory.The book has ten chapters; after an introductory chapter on basic definitions, the remaining chapters material on graph coloring; Hamiltonian cycles and Euler tours; extremal graph theory; subgraph counting problems including connections to permutations, derangements, and Cayley's formula; graph ...
The assets in financial portfolios are, for practical purposes, continuously divisible while portfolios of projects are "lumpy". For example, while we can compute that the optimal portfolio position for 3 stocks is, say, 44%, 35%, 21%, the optimal position for a project portfolio may not allow us to simply change the amount spent on a project.
Texas-based Frost Bank is getting back into the mortgage origination after 20 years away, eyeing an opportunity after the U.S. housing market just endured its worst year in over a decade.
The graph depicts an increase (that is, right-shift) in demand from D 1 to D 2 along with the consequent increase in price and quantity required to reach a new equilibrium point on the supply curve (S). A common and specific example is the supply-and-demand graph shown at right.
