Cap-prodcut structures on the Fintushel-Stern spectral sequence
Weiping Li
We show that there is a well-defined cap-product structure on the Fintushel-Stern spectral sequence. Hence we obtain the induced cap-product structure on the ${\BZ}_8$-graded insta…

Singular connection and Riemann theta function
Weiping Li
We prove the Chern-Weil formula for SU(n+1)-singular connections over the complement of an embedded oriented surface in smooth four manifolds. The expression of the representation…
