Well rewrite orderings and well quasi-orderings [PDF]
, 1991 Projet EURECAThis paper studies well (quasi) orderings described as rewrite orderings and proposes a new family of well (quasi) orderings that extends the embedding or divisibility order of G. Higman.

BPFA and projective well-orderings of the reals
The Journal of Symbolic Logic, 2011 AbstractIf the bounded proper forcing axiom BPFA holds and ω1 = ω1L, then there is a lightface Σ31 well-ordering of the reals. The argument combines a well-ordering due to Caicedo-Veličković with an absoluteness result for models of MA in the spirit of “David's trick.” We also present a general coding scheme that allows us to show that BPFA is ...

Measure, category and projective wellorders
Journal of Logic and Analysis, 2015 Summary: We show that each admissible assignment of \(\aleph_1\) and \(\aleph_2\) to the cardinal invariants in the Cichoń Diagram is consistent with the existence of a projective wellorder of the reals.

Narratives as Projective Techniques Among Psychology Students – A Content Analysis [PDF]
, 2010 This study is based on the writing of a short, potentially projective narrative, and sharing it in small peer groups. There is a close relationship between narratives and projection; readers‘ enjoyment may in fact depend on their ability and readiness to

Motions of Curves in the Projective Plane Inducing the Kaup-Kupershmidt Hierarchy [PDF]
, 2012 The equation of a motion of curves in the projective plane is deduced. Local flows are defined in terms of polynomial differential functions. A family of local flows inducing the Kaup-Kupershmidt hierarchy is constructed.

On Higher Syzygies of Projective Toric Varieties [PDF]
, 2006 Let A be an ample line bundle on a projective toric variety X of dimension n (≥ 2). It is known that the d-th tensor power A⊗d embedds X as a projectively normal variety in Pr := P(H0(X,L⊗d)) if d ≥ n − 1.
