Abstract: | For f: 0, ) R, the JMN approximant of f(t) is
where M and N are non-negative integers and ßk, i,Kiare defined constants. Under appropriate conditions on f andprovided Re( i) > 0
The approximants are the bases of recursions for numerical initial-valueproblems in linear differential-algebraic systems with constantcoefficients. The recursions are stable when N M N2.Each step of a recursion involves mainly the solution of N/2uncoupled algebraic systems. |
