High-Order Accuracy Approximation for a Two-Point Boundary Value Problem of Fourth Order with Degenerate Coefficients

Sobolev A.; Timerbaev M. (2018)

© 2018, Pleiades Publishing, Ltd. High-order accurate finite element schemes for a fourth-order ordinary differential equation with degenerate coefficients on the boundary are constructed. The method for solving the problem ...
Schemes of the finite element method with separation of singularity for a two-point boundary-value problem of the 4th order with degenerate coefficients

Sobolev A.; Timerbaev M. (2011)

In this paper we construct a high accuracy variant of the finite element method for an ordinary differential equation of the fourth order whose coefficients are degenerate on the boundary. The proposed technique is based ...
Volcanic pulses in the siberian traps as inferred from permo-triassic geomagnetic secular variations

Pavlov V.; Fluteau F.; Veselovskiy R.; Fetisova A.; Latyshev A.; Elkins-Tanton L.; Sobolev A.; Krivolutskaya N. (2015)

© Cambridge University Press 2015. There is little reason to believe that eruption of the Siberian Traps occurred gradually. On the contrary, trap emplacement likely occurred in the form of brief but voluminous volcanic ...
