oai:localhost:PNK-75672023-04-05T07:04:12Z Deformations and moduli of irregular canonical covers with K2=4pg−8 Purnaprajna, Bangere Francisco Javier, Gallego Jayan, Mukherjee satisfying K2=4pg−8 irregularity q CC BY In this article, we study the moduli of irregular surfaces of general type with at worst canonical singularities satisfying K2=4pg−8, for any even integer pg≥4. These surfaces also have unbounded irregularity q. We carry out our study by investigating the deformations of the canonical morphism φ:X→PN, where φ is a quadruple Galois cover of a smooth surface of minimal degree. These canonical covers are classified in Gallego and Purnaprajna (Trans Am Math Soc 360(10):5489-5507, 2008) into four distinct families, one of which is the easy case of a product of curves. 2023-04-05T07:04:12Z 2023-04-05T07:04:12Z 2023 Book https://link.springer.com/article/10.1007/s13163-023-00462-5 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7567 en application/pdf Springer |
