Generalized Albanese morphisms
We define generalizations of the Albanese variety for a projective variety X. The generalized Albanese morphisms X albr // _ _ _ Albr(X) contract those curves C in X for which the induced morphism Hom(π1(X),U(r)) → Hom(π1(C),U(r)) has a finite image. Thus, they may be interpreted as a U(r)-version of the Shafarevich morphism.
متن کاملGeneralization of -Centroidal Mean and its Dual
In this paper, the generalized -centroidal mean and its dual form in 2 variables are introduced. Also, studied some properties and prove their monotonicity. Further, shown that various means are partic- ular cases of generalized $bf{alpha}$-centroidal mean.
متن کاملGeneralized Lambda Distribution and its Properties
Generalized Lambda Distribution is an extension of Tukey's lambda distribution, that is very flexible in modeling information and statistical data. In this paper, We introduced two parameterization of this distribution. Then We estimate parameters by moment matching, percentile, starship and maximum likelihood methods and compare two parameterization and parameter estimation method...
متن کامل1-motivic Sheaves and the Albanese Functor
Using sheaf theoretic methods, we define functors Lπ0 : DMeff(k) → D(HI≤0(k)) and LAlb : DMeff(k) → D(HI≤1(k)). The functor LAlb extends the one in [3] to nonnecessarily geometric motives. These functors are then used to define higher Néron-Severi groups and higher Albanese sheaves.
متن کاملThe Hypergeometric Coupon Collection Problem and its Dual
Suppose an urn contains M balls, of different types, which are removed from the urn in a uniform random manner. In the hypergeometric coupon collection problem, we are interested in the set of balls that have been removed at the moment when at least one ball of each type has been removed. In its dual, we are interested in the set of removed balls at the first moment that this set contains all o...
