We are interested in relations among the invariants, which are natural generalizations of the "wall-crossing formula" and the "Witten conjecture" for classical Donaldson invariants. Our goal is to obtain a weaker version of these relations, by systematically using the intrinsic smoothness of moduli spaces. According to the recent excellent work of L. Goettsche, H. Nakajima and K. Yoshioka, the wall-crossing formula for Donaldson invariants of projective surfaces can be deduced from such a weaker result in the rank two case! 410 0$aLecture notes in mathematics (Springer-Verlag) ;$v1972. 606 $aSurfaces, Algebraic 606 $aInvariants 606 $aModuli theory 615 0$aSurfaces, Algebraic. 615 0$aInvariants. 615 0$aModuli theory. 676 $a516.35 686 $a14D20$a14J60$a14J80$2msc 686 $aMAT 142f$2stub 686 $aMAT 146f$2stub 686 $aSI 850$2rvk 700 $aMochizuki$b Takuro$f1972-$0319920 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910484256703321 996 $aDonaldson type invariants for algebraic surfaces$9230294 997 $aUNINA
