Abstract: The Cauchy problem for a nonlinear generalized pseudoparabolic equation is investigated. The well‐posedness of local strong solutions for the problem is established in the Sobolev space C([0, T); Hs(R))⋂ C1([0, T); Hs−1(R)) with s > 3/2, while the existence of local weak solutions is proved in the space Hs(R) with 1 ≤ s ≤ 3/2. Further, under certain assumptions of the nonlinear terms in the equation, it is shown that there exists a unique global strong solution to the problem in the space C([0, ∞); Hs(R))⋂ C1([0, ∞); Hs−1(R)) with s ≥ 2.
