Theory of valuations on manifolds, III. Multiplicative structure in the general case

The multiplicative structure on polynomial continuous valuations

We introduce a canonical structure of a commutative associative filtered algebra with the unit on polynomial smooth valuations, and study its properties. The induced structure on the subalgebra of translation invariant smooth valuations has especially nice properties (it is the structure of the Frobenius algebra). We also present some applications.

Theory of valuations on manifolds, IV. New properties of the multiplicative structure

This is the fourth part in the series of articles math.MG/0503397, math.MG/0503399, math.MG/0509512 where the theory of valuations on manifolds is developed. In this part it is shown that the filtration on valuations introduced in math.MG/0503399 is compatible with the product. Then it is proved that the Euler-Verdier involution on smooth valuations introduced in math.MG/0503399 is an automorphism of the algebra of valuations. Then an integration functional on valuations with compact support is introduced, and a property of selfduality of valuations is proved. Next a space of generalized valua…

Hard Lefschetz theorem for valuations and related questions of integral geometry

We study the properties of the multiplicative structure on valuations on convex sets. We prove a new version of the hard Lefschetz theorem for even translation invariant continuous valuations, and discuss related problems of integral geometry. Then we formulate a conjectural analogue of this result for odd valuations.

Theory of valuations on manifolds, I. Linear spaces

This is the first part of a series of articles where we are going to develop theory of valuations on manifolds generalizing the classical theory of continuous valuations on convex subsets of a linear space. In this article we still work only with linear spaces. We introduce a space of smooth (non-translation invariant) valuations on a finite dimensional linear space. We present three descriptions of this space. We describe the canonical multiplicative structure on it generalizing the results for polynomial valuations obtained by the author in Geom. Funct. Anal. 14 (2004).

Towards Hodge-Riemann relations for non-Archimedean analogs of valuations on convex sets

本文在非阿基米德类比空间中引入乘积与卷积两种乘法结构，提出混合硬 Lefschetz 定理和 Hodge-Riemann 关系的猜想，并证明乘积的度 1 与卷积的余度 1 的非混合 Hodge-Riemann 关系。
