源自$K$-理论的平移组合Hopf代数

Shifted combinatorial Hopf algebras from $K$-theory

Eric Marberg

AI总结:

该研究将此前与Lewis合作构建的峰拟对称函数Hopf代数的$K$-理论推广,纳入含六个Hopf代数的平移版$K$-理论组合Hopf代数图,得到经典峰代数的新$K$-理论类似物,还研究了相关$K$-理论Schur函数生成的Hopf代数并推导公式、提出开放问题。

摘要:

在先前与Lewis的合作工作中,我们构建了富集集值$P$-分拆理论,以构造峰拟对称函数Hopf代数的$K$-理论推广。本文中,我们将该对象置于一个含六个Hopf代数的图中,给出了Lam与Pylyavskyy所研究的$K$-理论组合Hopf代数图的平移版本。借此我们描述了经典峰代数的若干新$K$-理论类似物。我们还研究了由Ikeda和Naruse的$K$-理论Schur $P$-函数与$Q$-函数及其对偶生成的Hopf代数。研究过程中,我们推导了若干乘积、余积与对极公式,并概述了若干开放问题与猜想。

英文摘要:

In prior joint work with Lewis, we developed a theory of enriched set-valued $P$-partitions to construct a $K$-theoretic generalization of the Hopf algebra of peak quasisymmetric functions. Here, we situate this object in a diagram of six Hopf algebras, providing a shifted version of the diagram of $K$-theoretic combinatorial Hopf algebras studied by Lam and Pylyavskyy. This allows us to describe new $K$-theoretic analogues of the classical peak algebra. We also study the Hopf algebras generated by Ikeda and Naruse's $K$-theoretic Schur $P$- and $Q$-functions, as well as their duals. Along the way, we derive several product, coproduct, and antipode formulas and outline a number of open problems and conjectures.
