This paper explores intersections of memory and cinematic representation in contemporary Hungarian film culture. Since the fall of the Berlin Wall in 1989, with the concomitant financial crisis in Hungarian cinema, a number of films have foregrounded questions of Jewish identity, a taboo subject on Hungarian screens after 1945 when nationalistic historiography supported an official government culture of denial with regard to responsibility for the deportation and extermination of some 550 000 Hungarian Jews. The production of relatively few narrative and documentary films on this subject, the essay suggests, is perhaps in part attributable to the fact that the Hungarian uprising of 1956 tended to eclipse the drama of Jewish deportation and genocide. The authors consider post-socialist filmmakers’ uses of the past in the context of the country’s current nationalistic climate, interrogating the impact of controversal films such as László Nemes’s Son of Saul (2015, Grand Prix, Cannes Film Festival ; Academy Award for best foreign film) within a Hungarian society still conflicted about its Holocaust trauma.

Abstract  

We answer a question of Császár [12]: under which conditions a given pretopological closure or proximity can be induced by a Cauchy structure? We give a characterization for these closures and proximities using properties of convergences and nasses [14] induced by Cauchy structures. We prove also that the set of Cauchy screens inducing a given reciprocal convergence structure is a non empty interval of the set of Cauchy screens equipped with the usual inclusion order.

GPS navigation and SAR imaging systems performances depend on correct characterization of perturbations due to electromagnetic wave propagation through turbulent media such as ionosphere or troposphere. At these systems frequencies, ionospheric scintillations, which are more or less important according to geophysical conditions, must be studied as well as mean perturbations due to medium crossing.  After a description of ionospheric parameters, existing scintillation models are presented. Then, MPS and MPC numerical phase screens methods developed to simulate time series representative of ionospheric scintillations are described. These methods, which are applicable whatever the temporal and geographical localizations are, evaluate scintillation parameters close to analytical theoretical ones. Several  propagation conditions can be simulated such as propagation of a wide band source signal  or wave propagation through bidimensional anisotropic screens.
