Results 25 eyes were wide-angle(W) postoperatively, including 18 eyes W 4/4 circle,7eyes W 3/4 circle,10 eyes were N(narrow-angle) I ~N II. The differences (x2=68.00,P<0.001) betneen preopration and posoperation are remarkable.
We show that wonderful varieties are necessarily spherical (i.e., they are almost homogeneous under any Borel subgroup ofG).
This paper is devoted to a systematic study of quantum completely integrable systems (i.e., complete systems of commuting differential operators) from the point of view of algebraic geometry.
This implies that a system is algebraically integrable (i.e., its eigenvalue problem is explicitly solvable in quadratures) if and only if the differential Galois group is commutative for generic eigenvalues.
Let denote an orthogonal symmetric Lie algbra and let (G, K) be an associated pair, i.e., Lie(G = and Lie(K°) =.
Lower degree bounds for modular invariants and a question of I.
