In this paper the author first introduce a new concept of L
p
-dual mixed volumes of star bodies which extends the classical dual mixed volumes. Moreover, we extend the notions of L

-mixed intersection body. Inequalities for L
p
-dual mixed volumes of L
p
-mixed intersection bodies are established and the results established here provide new estimates for these type of inequalities.

The decomposition of the complete graph Kv into Kr×Kc's, the products of Kr and Kc,is originated from the use of DNA library screening. In this paper, we consider the case where r=2 and c = 5, and show that such a decomposition exists if and only if v ≡ 1 (mod 25). 相似文献

The largest class of multivalued systems satisfying the module-like axioms is the Hv-module. Hv-modules first were introduced by Vougiouklis. In this paper we define weak equality between two subsets of an Hv-module and introduced the notion of exact sequences of Hv-modules. Also some results on the weak equality and exact sequences are given. 相似文献
