论文摘要
我们研究了穿刺刺穿的riemann表面的特征品种的交点,并在穿刺周围有规定的单粒子。依靠Mellit的先前结果,用于半神经单层面,我们计算了与任何约旦类型的单粒子的角色品种的交集共同体。这证明了Letellier的猜想的庞加莱多项式专业化。
We study intersection cohomology of character varieties for punctured Riemann surfaces with prescribed monodromies around the punctures. Relying on previous result from Mellit for semisimple monodromies we compute the intersection cohomology of character varieties with monodromies of any Jordan type. This proves the Poincaré polynomial specialization of a conjecture from Letellier.
