Invariant Einstein metrics on generalized Wallach spaces have been classified except SO(k + l+ m)/SO(k) × SO(l) × SO(m). In this paper, we first give
We study the equation wtt + ?SN-1w-μwt-δw + h(t, ω)wp= 0,(t, ω) ∈ R × SN-1, and under some conditions we prove a monotonicity theorem for its positive
Suppose that X ={Xt, t≥0;Pμ} is a supercritical superprocess in a locally compact separable metric space E. Let φ0 be a positive eigenfunction corresponding
For a one parameter family of Calabi-Yau threefolds, Green et al.(2009) expressed the total singularities in terms of the degrees of Hodge bundles and Euler num
