论文摘要
我们表明,我们称之为上向对称的对称属性意味着kazhdan-lusztig $ r^x $ -polynomials a pircon $ p $是$ p $ -KERNEL,我们表明此属性在古典案例中具有。然后,我们增强并扩展到这种情况下,在抛物线kazhdan-lusztig理论中,deodhar的双重性。
We show that a symmetry property that we call the up-down symmetry implies that the Kazhdan--Lusztig $R^x$-polynomials of a pircon $P$ are a $P$-kernel, and we show that this property holds in the classical cases. Then, we enhance and extend to this context a duality of Deodhar in parabolic Kazhdan--Lusztig theory.
