significance for us to do oil and gas exploration.And sedimentology and diagenesis have many effects on the boundary through the research.The "lower boundary of buoyancy-controlled accumulation" has been studied through the analysis of porosity evolution model which was based on the following formula...
Recycling process and proto-kimberlite melt metasomatism in the lithosphere-asthenosphere boundary beneath the Amazonian Craton recorded by garnet xenocrysts and mantle xenoliths from the Carolina kimberlite[J].

In a recent paper with Thomas Hoffmann-Ostenhof, we proved that the number of critical points \(\ell _k\) in the boundary set of a minimal k-partition tends to \(+\infty \) as \(kightarrow +\infty \). In this note, we show that \(\ell _k\) increases linearly with k as sug...

In a Black and Scholes (1973) world, this paper studies the pricing performance of a closed-form lower bound to American option values based on an exercise strategy corresponding to a flat-exercise boundary. The lower bound has a simple two-step implementation akin to Barone-Adesi and Whaley...

We prove sharp lower bound estimates for the first nonzero eigenvalue of the non-linear elliptic diffusion operator Lp on a smooth metric measure space, without boundary or with a convex boundary and Neumann boundary condition, satisfying BE(κ,N) for κ≠0. Our results extends the work of ...

if E is a domain in or a Riemannian manifold (with or without boundary). The remaining Sects. 5–7 apply the abstract results to Lévy-type operators as in (1.1). Section 5 concerns the actual perturbation result and Sect. 6 the corresponding martingale problem. The concluding Sect. 7 ...
Linear partial differential equations with initial/boundary conditions are often approximated by linear finite difference equations which are solved either noniteratively using the Gauss Reduction method with partial pivoting (Krishnamurthy and Sen 2001; Sen 2002) or iteratively by the Gauss- Seidel/relaxat...
