Problem Find an expression for the solution x ( t , s , x 0 , p , q ) x(t, s, x_0, p, q) x ( t , s , x 0 , p , q ) of the initial value problem
x ′ = ( 1 + t 2 ) − q / 2 ∣ x ∣ p , x ( s ) = x 0 , p > 1 , q > 0 x' = (1 + t^2)^{-q/2}|x|^p, \quad x(s) = x_0, \quad p > 1, \quad q > 0 x ′ = ( 1 + t 2 ) − q /2 ∣ x ∣ p , x ( s ) = x 0 , p > 1 , q > 0
and its maximal existence time β ( s , x 0 , p , q ) \beta(s, x_0, p, q) β ( s , x 0 , p , q ) .
