Weakly Nonnegative Quadratic Forms,nd . positive roots of ., which can be used to characterize weak nonnegativity. We also describe . semi-unit forms, those forms not weakly nonnegative such that any proper restriction is weakly nonnegative. Diverse criteria for weak nonnegativity are provided, including Zeldych’s Theorem and a few aIntercept 发表于 2025-3-25 14:33:56

Positive Quadratic Forms, the theory of integral quadratic forms, . and ., are introduced in this chapter, and are used to provide a classification of positive unit forms in terms of .. A combinatorial characterization of such forms in terms of . is also presented.constellation 发表于 2025-3-26 09:07:24

ey are concerned mostly with dynamical sys tems in dimensions one and two, in particular with a view to their applications to foliated manifolds. An important chapter, however, is missing, which would have been dealing with structural stability. The publication of the French edition was re alized
