Abstract: We show that all the even canonical surfaces in a certain area of the zone of existence have non-reduced Kuranishi space. In particular, for a given irregularity, the existence of surfaces of general type with non-reduced moduli space is shown.

Keywords: Surface; moduli; fibration.

Classification (MSC2000): 14J29.
