In this paper, we give new criteria for affineness of a variety defined over C. Our main result is that an irreducible algebraic variety Y (may be singular) of dimension d (d ≥ 1) defined over C is an affine variety if and only if Y contains no complete curves, Hi(Y,OY ) = 0 for all i > 0 and the boundary X − Y is support of a big divisor, where X is a projective variety containing Y . We const...

We have derived solitary wave solutions of generalized KdV-type equations of fifth order in terms of certain hyperbolic functions and investigated their stability. It has been found that the introduction of more dispersive effects increases the stability range. 2000 Mathematics Subject Classification. 35Q53.

Across languages subject-verb agreement errors have been established when subjects are producing complex (NP PP) noun-phrases (see Bock, 1995, for an overview). Very recently, Haskell & MacDonalds (2002) proposed a locality-based principle, the principle of proximity, to explain a variety of agreement errors in production. They base they argument partly on preferences in verb number marking in ...

In this paper, compared with the previous results, a new global existence for strong solutions to the equation is acquired provided that the potential (1−∂2 x)u0 changes sign on R, which improves considerably the previous result. Mathematics Subject Classification: 35G25, 35L05, 35Q35

Reciprocals are characterized by a crossover of thematic roles within a single clause. Their peculiar semantics often creates special argument configurations not found in other clause types. While some languages either encode reciprocals by clearly divalent, transitive clauses, or clearly monovalent, intransitive clauses, others adopt a more ambivalent solution. We develop a typology of valency...

A mixed-typed differential inclusion with a weakly continuous nonlinear term and a nonmonotone discontinuous nonlinear multi-valued term is studied, and the existence and decay of solutions are established. 2000 Mathematics Subject Classification. Primary 34G20, 35M10, 35M20.

It is suggested here that an interesting and important line of inquiry is the elaboration of methods of inverse scattering transform (IST) type in contexts where non-homogeneous boundary conditions intercede. The issue, which has practical relevance we indicate by example, appears ripe for development, thanks to recent new ideas interjected into the panoply of IST methodologies. A sketch of the...

The analysis of basic clause structures shows that clauses in Bahasa Siladang consist verbal and non-verbal predication. predicate can be filled by an adjective, noun, numeral or prepositional phrase. the argument structure intransitive requires one NP as only functioning grammatical subject, which agent a patient. Meanwhile, transitive verb two more arguments. presence these arguments sentence...

An eye-tracking experiment examined whether prosodic cues can affect the interpretation of grammatical functions in the absence of clear morphological information. German listeners were presented with scenes depicting three potential referents while hearing temporarily ambiguous SVO and OVS sentences. While case marking on the first noun phrase (NP) was ambiguous, clear case marking on the seco...
