给出了方程ut(t,x)=<$t0k(t-s)σ(ux(s,x))xds + f(t,x)整体存在强解的充分条件.核k满足Rk(z)≥ κ| I k(z)|且σ随sup {σ′(p)}增大
Abstract Sufficient conditions for the global existence of a strong solution of the equation u t ( t , x ) = ∫ t 0 k ( t − s ) σ( u x ( s , x )) x ds + f ( t , x ) are given. The kernel k satisfies R k ( z ) ≥ κ | I k ( z ) | and σ is increasing with sup {σ′ ( p ) }
