    "abstract": "We discuss certain special cases of algebraic approximants that are given as\nzeroes of so-called \"effective characteristic polynomials\" and their\ngeneralization to a multiseries setting. These approximants are useful for the\nconvergence acceleration or summation of quantum mechanical perturbation\nseries. Examples will be given and some properties will be discussed.",
