Metric induced

We prove that in the pure mapping class group of the 3-punctured projective plane equipped with the word metric induced by certain generating set, the ratio of the number of pseudo-Anosov elements to the number of all elements in a ball centered at the identity tends to one, as the radius of the ball tends to infinity.

We study both radical transversal and transversal lightlike submanifolds of indefinite Sasakian manifolds. We give examples, investigate the geometry of distributions and obtain necessary and sufficient conditions for the induced connection on these submanifolds to be metric connection.

From the point of view of lifting to entire manifold, two types of polynomial substructures are distinguished according to the vanishing of not of the sum of the coefficients. Conditions of parallelism for the extended structure with respect to some remarkable linear connections are given in two forms, firstly in a global description and secondly using the decomposition in distributions.

We assume that the manifold with boundary, X, has a SpinC -structure with spinor bundle S Along the boundary, this structure agrees with the /. structure defined by an infinite order, integrable, almost complex structure and the metric is K¨hler. In this case the SpinC -Dirac operator . agrees with a ¯ ¯ ∂ + ∂ ∗ along the boundary. The induced CR-structure on bX is integrable and either strictly pseudoconvex or strictly pseudoconcave. We assume that E → X is a complex vector bundle, which has an infinite order, integrable, complex structure along bX, compatible with that defined...

We study several constrained variational problems in the 2-Wasserstein metric for which the set of probability densities satisfying the constraint is not closed. For example, given a probability density F0 on Rd and a time-step 2 h 0, we seek to minimize I(F ) = hS(F )+W2 (F0 , F ) over all of the probability densities F that have the same mean and variance as F0 , where S(F ) is the entropy of F . We prove existence of minimizers. We also analyze the induced geometry of the set of densities satisfying the constraint on...

The investment portfolio typically has a significant impact on an FHLBank’s total interest rate risk profile. While FHLBanks may manage the interest rate risk of its mortgage assets by combining AMA and MBS, and manage the economic value risk of the entire FHLBank through VaR metrics, it is nonetheless a sound practice to separately measure and control price sensitivity in the investment portfolio with limits for price changes given rate changes. For example, the FHLBank may limit the portfolio’s sensitivity to 10 percent when interest rates change 300 basis points.
