We classify triangulated categories that are equivalent to finitely generated thick subcategories T⊂Db(cohC) for smooth projective curves C over an algebraically closed field.

Finding forced collinearity relationship can be usefull in several domains of algorithmic geometry. In particular, in the GCS framework, it can help to detect bad-constrained systems. This paper deals with a simple framework where only incidence and collinarities are considered. We propose two methods to prove that a collinearity is a logical consequence of other specified collinearities. 1 GCS...

Projective techniques continue to be widely used by school psychologists despite frequent criticisms of their use. This article reviews contemporary validity issues in the use of projective techniques with children and adolescents, including incremental validity, treatment validity, and problems associated with professional judgment and experience. A discussion of these issues and their implica...

The term "projective tests" is customarily applied to several of the sharpest and most valuable weapons in the clinical psychologist's armoury. Some of these?the Rorschach test, for example?are well known; others are not, and indeed some depend for their effectiveness upon their deceptive similarity to verbal intelligence tests. There are, nevertheless, essential differences between them and th...

This book is a major contribution to the literature on delinquency. Professor Merrill surveys the resources of the clinician in the tasks of assessing social environment and understanding delinquent personalities; and she describes the use of intelligence tests and projective techniques. The behaviour of delinquent children is understandable only in terms of the basic needs of the individual ch...

In this paper, we formulate and prove a weighted homogeneous version of Zariski’s hyperplane section theorem on the fundamental groups of the complements of hypersurfaces in a complex projective space, and apply it to the study of π1(P 2 \C), where C ⊂ P is a projective plane curve. The main application is to prove a comparison theorem as follows. Let φ : P → P be the composition of the Verones...

Let C be a binary self-dual code with an automorphism g of order 2p, where p is an odd prime, such that g is a xed point free involution. If C is extremal of length a multiple of 24 all the involutions are xed point free, except the Golay Code and eventually putative codes of length 120. Connecting module theoretical properties of a self-dual code C with coding theoretical ones of the subcode C...

ABSTRACT: In this paper we improve the known bound for the X-rank RX(P ) of an element P ∈ PN in the case in which X ⊂ Pn is a projective variety obtained as a linear projection from a general v-dimensional subspace V ⊂ Pn+v . Then, if X ⊂ Pn is a curve obtained from a projection of a rational normal curve C ⊂ Pn+1 from a point O ⊂ Pn+1, we are able to describe the precise value of the X-rank f...

There exists a duality between elliptic curves and noncommutative tori, i.e. C∗-algebras generated by the unitary operators u and v such that vu = euv. We show that this duality can be included into a general picture involving the algebraic curves of higher genus. In this way we prove that a big part of geometry of complex algebraic curves can be developed from the K-theory of a noncommutative ...

Gupta and Ray (Fuzzy Sets and Systems 54 (1993) 191) introduced the notion of fuzzy projective planes. We show that an old theorem of Dembowski classi$es all $nite fuzzy projective planes, that the examples in Gupta and Ray (Fuzzy Sets and Systems 54 (1993) 191) arise from ordinary projective planes and have much easier descriptions that can easily be generalized, and that there exist fuzzy pro...
