We generalize the Harnack-Thom theorem to relate the ranks of the Lawson homology groups with ℤ₂-coefficients of a real quasiprojective variety with the ranks of its reduced real Lawson homology ...
We will show that, unlike usual (i.e., nonimpulsive) differential equations, the standard Sharkovsky cycle coexistence theorem applies easily to impulsive, scalar, ordinary differential equations. In ...
