4 FORMALITY OF k - CONNECTED SPACES IN 4 k + 3 AND 4 k + 4 DIMENSIONS GIL
Using the concept of s-formality we are able to extend the bounds of a Theorem of Miller and show that a compact k-connected (4k + 3)or (4k + 4)-manifold with bk+1 = 1 is formal. We study k connected n-manifolds, n = 4k + 3, 4k + 4, with a hard Lefschetzlike property and prove that in this case if bk+1 = 2, then the manifold is formal, while, in 4k+3-dimensions, if bk+1 = 3 all Massey products ...
متن کاملPhilos plate fixation for proximal humeral fractures.
PURPOSE To evaluate the efficacy of Philos plate fixation for proximal humerus fractures. METHODS Functional outcomes of 31 men and 27 women aged 36 to 73 (mean, 61) years who underwent Philos plate fixation for proximal humeral fractures were retrospectively reviewed. Indications for surgery were 3-part (n=33) or 4-part (n=25) closed proximal humeral fractures with angulation of more than 45...
متن کامل137 ExSpherium
A quasi-exactly solvable model is one for which it is possible to solve the Schrödinger equation exactly for a finite portion of the energy spectrum [1]. In quantum chemistry, a famous example of this is the Hooke’s law atom [2–5], which consists of a pair of electrons, repelling Coulombically but trapped in a harmonic external potential. This model and others [6–12] have been used extensively ...
متن کاملUnique representation d = 4 k ( k 2 − 1 ) in D ( 4 ) - quadruples { k −
Let k ≥ 3 be an integer. We show that if d is a positive integer such that the product of any two distinct elements of the set {k−2, k+2, 4k, d} increased by 4 is a square, then d must be 4k(k2−1).
متن کاملUnsatisfiable (k,(4*2^k/k))-CNF formulas
A Boolean formula in a conjunctive normal form is called a (k, s)-formula if every clause contains exactly k variables and every variable occurs in at most s clauses. We show that there are unsatisfiable (k, 4 · 2 k
