چکیده انگلیسی
We describe the thickened strips and introduce the outside nested decompositions of any skew shape λâμ. For any such decomposition Φ=(Î1,Î2,â¦,Îg) of the skew shape λâμ where Îi is a thickened strip for every i, let r be the number of boxes that are contained in any two distinct thickened strips of Φ. Then we establish a determinantal formula of the function p1r(X)sλâμ(X) with the Schur functions of thickened strips as entries, where sλâμ(X) is the Schur function of the skew shape λâμ and p1r(X) is the power sum symmetric function indexed by the partition (1r). This generalizes Hamel and Goulden's theorem on the outside decompositions of the skew shape λâμ and our extension is motivated by the enumeration of m-strip tableaux, which was first counted by Baryshnikov and Romik via extending the transfer operator approach due to Elkies.
