A Simple Proof for the Existence of Zariski Decompositions on Surfaces
The decomposition D = P + N is called the Zariski decomposition of D, the divisors P and N are respectively the positive and negative parts of D. Zariski’s result has been used to study linear series on surfaces, and in the classification of surfaces (see [1, Chapt. 14] and [4, Sect. 2.3.E], as well as the references therein). We also mention that there is an extension to pseudo-effective divis...
متن کاملTensor Decompositions and Sparse Log-linear Models.
Contingency table analysis routinely relies on log-linear models, with latent structure analysis providing a common alternative. Latent structure models lead to a reduced rank tensor factorization of the probability mass function for multivariate categorical data, while log-linear models achieve dimensionality reduction through sparsity. Little is known about the relationship between these noti...
متن کاملRestricted Volumes and Divisorial Zariski Decompositions
We give a relation between the existence of a Zariski decomposition and the behavior of the restricted volume of a big divisor on a smooth (complex) projective variety. Moreover, we give an analytic description of the restricted volume in the line of Boucksom’s work. It enables us to define the restricted volume of a transcendental class on a compact Kähler manifold in natural way. The relation...
متن کاملOn the existence of prime decompositions
We investigate factorizations of regular languages in terms of prime languages. A language is said to be strongly prime decomposable if any way of factorizing it yields a prime decomposition in a finite number of steps. We give a characterization of the strongly prime decomposable regular languages and using the characterization we show that every regular language over a unary alphabet has a pr...
متن کاملThe existence of Bogomolny decompositions for gauged baby Skyrme models
The Bogomolny decompositions (Bogomolny equations) for the gauged baby Skyrme models: restricted and full one, in (2+0)-dimensions, are derived, for some general classes of the potentials. The conditions, which must be satisfied by the potentials, for each of these mentioned models, are also derived.
