We generalize the Hart-Shelah example [10] to higher infinitary logics. We build, for each natural number and for each infinite cardinal λ, a sentence of the logic that (modulo mild set theoretical hypotheses around λ and assuming ) is categorical in but not in (or beyond); we study the dimensional encoding of combinatorics involved in the construction of this sentence and study various model-theoretic properties of the resulting abstract elementary class in the finite interval of cardinals .

我们将Hart-Shelah示例[10]推广到更高的无限逻辑。我们为每个自然数建立对于每个无限基数λ,一个句子 逻辑的 那(模温和集合理论假设在λ附近并且假设)属于以下类别 但不在 (或更高);我们研究了构成该句子的组合词的维数编码,并研究了所得抽象基本类的各种模型理论性质 在红衣主教的有限区间内 。
