This article studies a combined primality test for natural numbers, called \textit{L2 test}, by combining the Lucas test and the Fermat condition test. The efficiency and complexity of this test are also analyzed, and a methodology for identifying composite numbers that pass the L2 test (called L2 pseudoprimes) is presented.

Mathematics of Computation, 1986
This paper contains a rather detailed description of the methods used for proving the primality of \(R_{1031}\) where \(R_ n=(10^ n-1)/9\) is a so-called repunit number. The interest in numbers of this kind stems from the fact (due to the second author) that the only repunit primes \(R_ n\) for \(n\leq 10 000\) are \(R_ 2\), \(R_{19}\), \(R_{23 ...

Primal Fatherhood and Primal Rage
The American Journal of Psychoanalysis, 2007Fatherhood may unconsciously activate repudiated identifications with patriarchal primal fathers in men with progressive social values. These men may consciously cultivate an image of themselves as rebellious nonconformists. These men may wish to raise children who are fiercely independent just like them.

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
In this paper we introduce a novel representation of the significant changes in curvature along the bounding contour of planar shape. We call the representation the Curvature Primal Sketch because of the close analogy to the primal sketch representation advocated by Marr for describing significant intensity changes.

Topology and its Applications, 2022
In the context of \(k\)-primal spaces, the authors prove that a topology with finite specialization qoset \((X,\leq)\) is \(k\)-primal for some positive integer \(k\), if and only if for any cyclic point \(a\) and any \(x\) and \(y\) in \(X\) such that \(a\leq y\) and \(x\leq y\) it happens that \(a\leq x\).

Intuition IV. Primal images and primal judgment
The Psychiatric Quarterly, 19551. Schizophrenia, borderline conditions, and neuroses often involve highly cathected, pathogenic images of a special type, which are archaic relics from infancy and childhood and have not undergone the normal processes of modification and resolution.

Mathematical Logic Quarterly, 1987
It is known for a primal algebra \b{A}\(=\) that there exist 9 clones of operations on \(A\times A\) extending the clone of \b{A}\(\times \underline A\). The resulting algebras are called ``squares'' of \b{A} in this paper. The paper gives a new proof of the existence of these 9 clones based on the Baker-Pixley theorem and investigates in more detail 3

Flat unars: the primal, the semi-primal and the dualisable
Algebra universalis, 2010A flat unar is a semilattice of height one with an additional unary operation. In the paper, the primal, semi-primal and dualisable finite flat unars are characterized. A useful characterization of primality in general is given using an array of techniques from the theory of natural dualities.

This paper attempts to indicate some of the strengths and weakenesses of primal therapy, some of the ways it is changing and how it can be incorporated within more traditional psychodynamic frames of reference.
