Nonstandard finite difference schemes for differential equations
In this paper, the reorganization of the denominator of the discrete derivative and nonlocal approximation of nonlinear terms are used in the design of nonstandard finite difference schemes (NSFDs). Numerical examples confirming then efficiency of schemes, for some differential equations are provided. In order to illustrate the accuracy of the new NSFDs, the numerical results are compared with ...

متن کاملBifunctor Cohomology and Cohomological Finite Generation for Reductive Groups
LetG be a reductive linear algebraic group over a field k. LetA be a finitely generated commutative k-algebra on which G acts rationally by k-algebra automorphisms. Invariant theory states that the ring of invariantsA = H 0(G,A) is finitely generated. We show that in fact the full cohomology ringH ∗(G,A) is finitely generated. The proof is based on the strict polynomial bifunctor cohomology cla...
