Polynomials close to 0 resp. 1 on disjoint sets
For disjoint compact subsets I, J of a real interval [A, B] construction is given for polynomials P-n of degree n = 1,2,... that approximate 0 on I and 1 on J with geometric rate, vanish (in a given order) at finitely many given points of I, take the value 1 (in a given order) at finitely given poin...
