On independent rigid classes in $H^{*}(\operatorname{WU}_{q})$

Taro Asuke

Full-text: Open access


We introduce a family of rigid, linearly independent classes in $H^{*}(\operatorname{WU}_{q})$. The family is different from the one studied by Hurder in (Invent. Math. 66 (1982), 313–323), and some of the classes are decomposed into products of elements of $H^{*}(\operatorname{WU}_{q})$. We will show the independence by examining a complexification of Baker’s example in (Comment. Math. Helv. 53 (1978), 334–363).
