These are the classes of varieties which appear only in characteristic 2 and they show that the hodge number formula for G¨ottsche-Soergel does not hold over haracteristic 2. It also gives examples of varieties with trivial canonical class which are neither irreducible symplectic nor Calabi-Yau, thereby showing that there are strictly more classes of simply connected varieties with trivial canonical class in characteristic 2 than over C as given by Beauville-Bogolomov decomposition theorem."}],"doi":"10.1016/j.bulsci.2021.102957","arxiv":1,"day":"01","isi":1,"external_id":{"isi":["000623881600009"],"arxiv":["2010.08976"]},"date_updated":"2023-08-07T13:47:48Z","citation":{"ama":"Srivastava TK.

Our varieties are defined through polynomials in many variables and part of our work is devoted to establishing Schinzel's hypothesis for polynomials of this kind. This last part is achieved by using arguments behind Birch's well-known result regarding the Hasse principle for complete intersections with the notable difference that we prove our result in 50% fewer variables than in the classical Birch setting. We also study the problem of square-free values of an integer polynomial with 66.6% fewer variables than in the Birch setting.","lang":"eng"}],"doi":"10.1016/j.bulsci.2019.102794","arxiv":1,"day":"01","isi":1,"external_id":{"arxiv":["1801.03082"],"isi":["000496342100002"]},"date_updated":"2023-08-29T07:18:02Z","citation":{"apa":"Destagnol, K.
