چکیده
In this paper we classify endofunctors on the simplex category, and we identify those that induce weak equivalence preserving functors on the category of simplicial sets.

Subdivisions of Toric Complexes
We introduce toric complexes as polyhedral complexes consisting of rational cones together with a set of integral generators for each cone, and we define their associated face rings. Abstract simplicial complexes and rational fans can be considered as toric complexes, and the face ring for toric complexes extends Stanley and Reisner’s face ring for abstract simplicial complexes [20] and Stanley...
متن کاملA Comparison of pical Root Resorption in Incisors after Fixed Orthodontic Treatment with Standard Edgewise and Straight Wire (MBT) Method
STATEMENT OF PROBLEM One of the major outcomes of orthodontic treatment is the apical root resorption of teeth moved during the treatment. Identifying the possible risk factors, are necessary for every orthodontist. PURPOSE The aim of this study was to compare the rate of apical root resorption after fixed orthodontic treatment with standard edgewise and straight wire (MBT) method, and also t...
متن کاملAnalysis of pain level in cases treated with Invisalign aligner: comparison with fixed edgewise appliance therapy
BACKGROUND The aim of this study was to evaluate and compare the difference in the level of pain using the visual analog scale (VAS) between cases treated with the edgewise appliance and Invisalign. In addition, the cause of pain and discomfort in the Invisalign cases was identified. METHODS The sample consisted of 145 cases for the edgewise group (EG; n=55), Invisalign group (IG; n=38), and ...

*Correspondence: [email protected] Department of Mathematics, Faculty of Science, Cumhuriyet University, Sivas, 58 410, Turkey Abstract The discrete generalized Cesàro matrix At = (ank) is the triangular matrix with nonzero entries ank = tn–k/(n + 1), where t ∈ [0, 1]. In this paper, boundedness, compactness, spectra, the fine spectra and subdivisions of the spectra of discrete gene...
متن کاملThe Generalized Baues Problem for Cyclic Polytopes II Preprint SC 98-43 (Januar 1999) THE GENERALIZED BAUES PROBLEM FOR CYCLIC POLYTOPES II
Given an affine surjection of polytopes : P ! Q, the Generalized Baues Problem asks whether the poset of all proper polyhedral subdivisions of Q which are induced by the map has the homotopy type of a sphere. We extend earlier work of the last two authors on subdivisions of cyclic polytopes to give an affirmative answer to the problem for the natural surjections between cyclic polytopes : C(n; ...
