چکیده
In this paper, we introduce the notion of “(n, d)-perfect rings” which is in some way a generalization of the notion of “S-rings”. After we give some basic results of this rings and we survey the relationship between “A(n) property” and “(n, d)-perfect property”. Finally, we investigate the “(n, d)-perfect property” in pullback rings.

We prove that any nonconstant entire holomorphic curve f : C → X in a projective algebraic hypersurface X ⊂ P(C) of arbitrary dimension n > 2 must be algebraically degenerate if X is generic and if its degree satisfies the effective lower bound degX > n n+5 . Table of contents

Using the method of Tracy and Widom we rederive the correlation functions for β = 1 Hermitian and real asymmetric ensembles of N ×N matrices with N odd.

We attack two problems here: First, we want to combine a modal accessibility relation with a preferential relation in a modal language. This problem is solved by adding a complementary modality. Second, we want to characterize obligations syntactically and semantically. This problem is solved sytactically by suitable disjunctions of conjunctions but not negations. Semantically, we define a Hamm...
