High‐order multigrid strategies for hybrid high‐order discretizations of elliptic equations
Numerical Linear Algebra with Applications, Volume 30, Issue 1, January 2023., 2023 Abstract This study compares various multigrid strategies for the fast solution of elliptic equations discretized by the hybrid high‐order method. Combinations of h$$ h $$‐, p$$ p $$‐, and hp$$ hp $$‐coarsening strategies are considered, combined with diverse intergrid transfer operators.

Tropicalization of 1-tacnodal curves on toric surfaces [PDF]
arXiv, 2017 A degeneration of a singular curve on a toric surface, called a tropicalization, was constructed by E. Shustin. He classified the degeneration of 1-cuspidal curves using polyhedral complexes called tropical curves. In this paper, we define a tropical version of a 1-tacnodal curve, that is, a curve having exactly one singular point whose topological ...

ON THE GENUS OF CURVES OF AN ALGEBRAIC SYSTEM [PDF]
Transactions of the American Mathematical Society, 1949 Professor C. Chevalley has recently pointed out to me the desirability of having a simple algebraic proof of the following theorem: The genus of any curve of an algebraic system of algebraic curves is not greater than the genus of the generic curve of the system.

International Journal for Numerical Methods in Engineering, Volume 124, Issue 1, Page 119-158, 15 January 2023., 2023 Abstract In the quest for a numerical method for surface waves and wave‐induced effects applicable when linear or weakly nonlinear methods are insufficient, a three‐dimensional numerical wave tank assuming fully‐nonlinear potential‐flow theory is proposed.

Real algebraic curves, the moment map and amoebas [PDF]
Ann. of Math. (2) 151 (2000), no. 1, 309--326, 2000 In this paper we prove the topological uniqueness of maximal arrangements of a real plane algebraic curve with respect to three lines. More generally, we prove the topological uniqueness of a maximally arranged algebraic curve on a real toric surface.
