circle actionstable complex structurerigid multiplicative genusWe prove that if the circle group acts smooth and unitary on 2n-dimensional stably complex manifold with two isolated fixed points and it is not bound equivariantly, then n=1 or 3. Our proof relies on the rigid Hirzebruch genera....

Thus, the points P and Q on the curve have coordinates (x,1). Step 5: Find point P on the circleThe point P also lies on the circle defined by:x2+y2=10Substituting y=1:x2+12=10x2+1=10x2=9Thus, x=3 or x=−3. However, x=−3 is not valid since it makes the ...
