关于ω-强凸空间的一点注记

本文研究了关于ω-强凸空间和ω-强光滑空间的问题.利用Banach理论的方法,证明了ω-强凸空间和ω-强光滑空间是一对对偶概念,并讨论了ω-强光滑性与其它光滑性之间的关系,用切片统一刻画了ω-强凸空间与ω-强光滑空间的特征,完善了ω-强凸空间及其对偶空间的研究.     

八元瓜环对1,ω-二(2-氨基吡啶)烷烃光致环加成反应的超分子催化性能的研究

合成了三种不同链长的1,ω-二(2-氨基吡啶)烷烃,分别为二溴化1,4-二(2-氨基吡啶)丁烷(C4)、二溴化1,6-二(2-氨基吡啶)己烷(C6)、二溴化1,8-二(2-氨基吡啶)辛烷(C8).考察了八元瓜环(Q[8])与上述三种1,ω-二取代烷烃的主客体相互作用,运用1H NMR及UV-vis证明三种客体与Q[8]的作用模式均不相同.在此基础上,考察了八元瓜环对三种底物光致环加成反应的超分子催化性能.结果表明,由于三种底物与Q[8]的主客体作用模式不同,八元瓜环对它们光二聚反应的超分子催化性能也各有差异.

液晶冠醚4—（烯丙基氧）—4′—（4′—羧基苯并—15—冠—5）联苯的变温红外光谱和拉曼光谱研究

本文用红外光谱法和激光拉曼光谱法研究了液晶冠醚４一（烯丙基氧）一４′一（４′一羧基苯并一１５一冠一５）联苯在升温时从结晶态到液晶态再到各向同住的液态相转变过程中红外光谱和拉曼光谱的变化。对该液晶冠醚的红外和拉曼特征频串进行了初步的经验式归属，并以频率位移、相对强度及峰形的变化描述了该化合物的相转变并初步讨论了相转变过程中光谱信息与分子结构的关系。     

One-pot synthesis of ω-bromoesters from aromatic aldehydes and diols using pyridinium hydrobromide perbromide

A simple and efficient one-pot procedure has been developed for the synthesis of ω-bromoesters from aromatic aldehydes and diols in the presence of pyridinium hydrobromide perbromide (PHPB) and triethoxymethane in which aldehyde reacts first with diol and the product, cyclic acetal, reacts with PHPB to give the final product, ω-bromoesters.     

On Factorizations of Baer-Local Formations

Abstract

It is proved that if the product ? of formations 𝔐 and ? ≠ ? is either a Baer-local formation or an ω-local formation and if ? ? 𝔉 for some one-generated ω-local formation 𝔉, then 𝔐 is also an ω-local formation.     

Some embedding theorems for Hörmander-Beurling spaces

In this paper we prove a number of results on sequence space representations and embedding theorems of Hörmander-Beurling spaces. As a consequence and using sharp results of Meise, Taylor and Vogt, a result of Kaballo on short sequences and hypoelliptic operators is extended to ω-hypoelliptic differential operators and to the vector-valued setting.     

A characterization of some weighted inequalities for the vector-valued weighted maximal function
