If one compares the allowed region of the unitarity triangle of today with that of the early 1990’s [4] it is clear that the current region is considerably smaller. Although the errors on virtually all measurements have decreased since the early 1990’s, the single most important improvement...
However, this can fail if one just assumes symmetry, or symmetry and positive definiteness. A well-known example occurs when is the Hilbert space , is the space of test functions, and is the one-dimensional Laplacian . Then is symmetric and positive, but the operator does not have dense ...
s delta hedge is no longer accurate; they are short too much of the underlying security. If thespot marketopens higher on Monday, the trader has to buy back deltas to cover their position and reestablish a delta-neutral stance. Special attention is needed around a charm’s expiration time...

Theorem 1 Let be any totally positive matrix (thus, every minor has a non-negative determinant). Then for any -tuples of increasing elements of , one has where denotes the minor formed from the rows in and columns in . For instance, if is the matrix for some real numbers , one has ...
