论文摘要
对称的Grothendieck多项式概括了schur多项式，并且按程度是schur阳性的。从组合上看，这表现为Set值tableaux对Semistard Young Tableaux的概括。我们定义了一个（弱）对称$ p $ -grothendieck多项式，该多项式以相同的方式概括了$ p $ -schur多项式。合并从组合中，这表现为通过一种新型的tableaux概括了偏移的semistard Young Tableaux，我们称之为移动的多发表tableaux。
The symmetric Grothendieck polynomials generalize Schur polynomials and are Schur-positive by degree. Combinatorially this is manifested as the generalization of semistandard Young tableaux by set-valued tableaux. We define a (weak) symmetric $P$-Grothendieck polynomial which generalizes $P$-Schur polynomials in the same way. Combinatorially this is manifested as the generalization of shifted semistandard Young tableaux by a new type of tableaux which we call shifted multiset tableaux.
