We are interested in a class of groups, quasi-Frobenius groups (with involutions), whose internal structure generalizes that of the classical groups GA1(C), PGL 2(C) and SO3(R) : a subgroup and its conjugates, of finite index in their normalizer and trivial mutual intersection, cover"generically"the ambient group. From the perspective of model theory, we work with the hypothesis of the existence of a good notion of dimension on definable sets (we must distinguish between the o-minimal case and the ranked case). We pay special attention to the ranked case.

我们对一类内部结构推广经典群GA1(C)、PGL 2(C)和SO3(R)的拟frobenius群(有对合)感兴趣:在它们的归一化器上具有有限指数和平凡互交的子群及其共轭，“一般地”覆盖周围群。从模型论的角度来看，我们研究了在可定义集合上存在一个好的维度概念的假设(我们必须区分0最小情况和排名情况)。我们特别注意排位的情况。通过研究由对合引起的关联的几何学，我们给出了拟Frobenius群的分类，从而确定了在什么条件下经典群可以在一个维度框架中被识别为-- -- Nous Nous int ' essons '，一个类群，几个拟Frobenius群(平均对合)，没有一个结构区间g'en '实现细胞des groups classiques GA1(C)， PGL2(C)和SO3(R)。unsous -group et ses conjugu ' s, d' index fini dans ' leur normalisateur et d'intersection mutuelle triviale, reverent ' g 'en ' ericement ' le group ambiant。从透视的角度看，“模型的理论”、“模型的理论”、“假设的理论”、“存在的理论”、“可定义的理论”维度、“可定义的理论”维度、“最小的理论”维度、“可定义的理论”维度、“可定义的理论”维度、“可定义的理论”维度、“最小的理论”维度、“可定义的理论”维度、“可定义的理论”维度。我们需要特别注意的是，我们需要注意的是，我们需要注意的是，我们需要注意的是。在研究中，研究人员使用了一种新的方法，即在类群的分类中使用了一种新的方法，即在类群的分类中使用了一种新的方法，即在类群的分类中使用了一种新的方法，即在类群的分类中使用了一种新的方法，即在类群的分类中使用一种新的方法。

Given a complete theory $T$ and a subset $Y subseteq X^k$, we precisely determine the {em worst case complexity}, with respect to further monadic expansions, of an expansion $(M,Y)$ by $Y$ of a model $M$ of $T$ with universe $X$. In particular, although by definition monadically stable/NIP theories are robust under arbitrary monadic expansions, we show that monadically NFCP (equivalently, mutually algebraic) theories are the largest class that is robust under anything beyond monadic expansions. We also exhibit a paradigmatic structure for the failure of each of monadic NFCP/stable/NIP and prove each of these paradigms definably embeds into a monadic expansion of a sufficiently saturated model of any theory without the corresponding property.
