Λ(fl)= Λ(v * K I 2 K [v * K fc)]u*,fc= 1 fc= 1,* 表示Rn中的卷积。本文讨论了n > 2和V(x)=| x |~(0 < 7 < n)的情形.系统(1)-(2)在量子力学中作为费米N体系统的近似而出现,被称为含时Hartree-Fock型方程。在整个论文中,我们使用以下符号:N {1,2,3,-..},V(θ/dxtd/dxn),U(t)= exp(ftΔ/2),M(t)exp(i | x |/2t),J = U(i)xU(-t)= M(t)(i t)M(-t).对于1 < p <0,p' = p/(p-1),δ(p)= n/2 n/p。||||p表示L(R)的范数(如果p = 2,我们写为||||第2项=||||).对于1 < g,r <00并且对于间隔k R,||||g,r,l表示L(l;L <<(R))的范数r/q ',即,|| u || q,r,l = I /(l | u(t,x)| dx } dt,l整数l,并且m,r,l> m表示被定义为l / r的Hubert空间。
Λ (fl) = Σ (v * K I 2 K Σ [v * K ϋfc)]u*, fc=l fc=l and * denotes the convolution in R n . In this paper we treat the case n > 2 and V(x) = \x\~~ with 0 < 7 < n. The system (l)-(2) appears in the quantum mechanics as an approximation to a fermionic N-body system and is called the time-dependent Hartree-Fock type equation. Throughout the paper we use the following notation: N {1,2,3,-..}, V (θ/dxit td/dxn), U(t) = exp(ftΔ/2),M(t) exp(i\x\/2t), J = U(i)xU(-t) = M(t)(itV)M(-t). For 1 < p < oo, p' = p/(p-l), δ(p) = n/2 n/p. || | |p denotes the norm of L (R) (if p = 2, we write || | |2 = || ||). For 1 < g, r < oo and for the interval / c R, || ||g,r,/ denotes the norm r/q ' of L (/;L«(R)), namely, \\u\\q,r,ι = I / ( / \u(t,x)\ dx } dt τι integers / and m, Σ ί > m denotes the Hubert space defined as l / r
