Is it true that every immersion of a complex projective n-space in a Euclidean m-space satisfies ∫ |H|^(2n) dV ≥ ((2(n+1)π/n)^n/π! ?

In the question given above, H is the mean curvature of the immersed complex projective space in the Euclidean m-space

Do there exist non-mass-symmetric 2-type surfaces lying fully in a hypersphere of Euclidean 5-space?

A compact submanifold lying in a hypersphere Sm of a Euclidean (m+1)-space Em+1 is call mass-symmetric if the center of mass of M is the center of the hypersphere.

What are the relations between #_2(M) of a compact symmetric space M and the smallest number of cells needed to have a CW-complex structure on M?

For a compact symmetric space M, the 2-number #2(M) is the maximal possible cardinality of a subset A2(M) of M such that the point symmetry sx fixes every point of A2(M) for every x ∈ A2(M) (see...
