 Fortunately, talk of national styles in mathematics does not have to carry with it all the implications that were found in Bieberbach. Indeed, when historians today refer to national styles they do so without the nationalism that motivated the older contributions. Rather, they are concerned with describing how “local” cultures play a role in the constitution of knowledge (see also Larvor 2016). While increased mobility and email communications make it harder for national styles to thrive, special political conditions might also favor the persistence of such a style. This is the case, for instance, of the Russian style in algebraic geometry and representation theory. As Robert MacPherson has pointed out to the author, this case of national style would deserve a more extensive investigation and it would be interesting to study how the fall of the Soviet Union impacted this style. By contrast, an instance of a national style that has been extensively studied is that of Italian style algebraic geometry. This case has been studied with care by a number of historians of mathematics and in particular by Aldo Brigaglia (see also Casnati et al. 2016). For instance in a recent article, Brigaglia writes:
