The $L^2$-norm of the Euler class for Foliations on closed irreducible Riemannian 3-Manifolds

Dmitry V. Bolotov

An upper bound for the $L^2$- norm of the Euler class $e(\mathcal{F})$ of an arbitrary transversally orientable foliation $\mathcal{F}$ of codimension one, defined on a three-dimensional clo…
