Class number bounds and Catalan's equation
We improve a criterion of Inkeri and show that if there is a solution to Catalan’s equation x − y = ±1, (1) with p and q prime numbers greater than 3 and both congruent to 3 (mod 4), then p and q form a double Wieferich pair. Further, we refine a result of Schwarz to obtain similar criteria when only one of the exponents is congruent to 3 (mod 4). Indeed, in light of the results proved here it ...
متن کاملCriterion for polynomial solutions to a class of linear differential equation of second order
We consider the differential equations y = λ0(x)y ′ + s0(x)y, where λ0(x), s0(x) are C −functions. We prove (i) if the differential equation, has a polynomial solution of degree n > 0, then δn = λnsn−1 − λn−1sn = 0, where λn = λ ′ n−1 + sn−1 + λ0λn−1 and sn = s ′ n−1 + s0λk−1, n = 1, 2, . . . . Conversely (ii) if λnλn−1 6= 0 and δn = 0, then the differential equation has a polynomial solution o...
متن کاملAn optimality criterion for the crossing number
A sufficient condition is given that a certain drawing minimizes the crossing number. The condition is in terms of intersections in an arbitrary set system related to the drawing, and is like a correlation inequality.
متن کاملAppendix: the Selection Criterion Equation
The CURDS data set contains detailed information on the level of ownership of CNCs by each firm in the sample incorporating date of first adoption. This allows us to classify the sample firms in 1993 into 4 categories: non adopters; currently diffusing users; complete users; and ex users. Of the total sample of 343 firms, 59 firms were excluded on the grounds that CNC was not an appropriate tec...
متن کاملA New Class Cohesion Criterion:
Class cohesion is considered as one of important object-oriented software attributes. Cohesion refers to the degree of the relatedness of the members in a class. High cohesion is a desirable property of classes. Several metrics have been proposed in the literature in order to measure class cohesion in object-oriented systems. They capture class cohesion in terms of connections among members wit...
