It is divided into three parts. In the first part, we study categories of finite-dimensional modules over the periplectic Lie superalgebras $mathfrak{p}(n)$ and obtain a BGG type reciprocity. In particular, these categories have only finitely-many blocks. We also compute the characters for irreducible modules over periplectic Lie superalgebras of ranks $2$ and $3$, and obtain explicit description of the blocks for ranks $2$, $3$, and $4$. In the second part, we develop a reduction procedure which provides an equivalence from an arbitrary block of the BGG category for the queer Lie superalgebra $mathfrak{q}(n)$ to a block with weights in $Lambda_{{ell_1},s_{1}}(n_1) imes cdots imes Lambda_{{ell_k},s_{k}}(n_{k})$ (see, Theorem ef{FirstMainThm}) for a BGG category of finite direct sum of queer Lie superalgebras. The descriptions of blocks are given as well. We also establish equivalences between certain maximal parabolic subcategories for $mathfrak{q}(n)$ and blocks of atypicality-one of the category of finite-dimensional modules for $mathfrak{gl}(ell|n-ell)$, where $ell leq n$. In the third part, we establish a maximal parabolic version of the Kazhdan-Lusztig conjecture cite[Conjecture 5.10]{CKW} for the BGG category $mathcal{O}_{k,zeta}$ of $mathfrak{q}(n)$-modules of ``$pm zeta$-weights'', where $kleq n$ and $zetainCsetminushf $. As a consequence, the irreducible characters of these $mathfrak q(n)$-modules in this maximal parabolic category are given by the Kazhdan-Lusztig polynomials of type $A$ Lie algebras. As an application, closed character formulas for a class of $mathfrak q(n)$-modules resembling polynomial and Kostant modules of the general linear Lie superalgebras are obtained.2542351 bytesapplication/pdf論文公開時間: 2021/6/11論文使用權限: 同意有償授權(權利金給回饋學校)Periplectic 李超代數不可約特徵標BGG 型之互反律Queer 李超代數BGG 範疇Kazhdan-Lusztig 型猜想Periplectic Lie superalgebrairreducible characterBGG reciprocityqueer Lie superalgebraBGG categoryKazhdan-Lusztig conjecturethesis10.6342/NTU201600258http://ntur.lib.ntu.edu.tw/bitstream/246246/276754/1/ntu-105-D00221002-1.pdf
