چکیده
In this paper we discuss metric cell complexes satisfying a coarse form of 2-dimensional Poincaré duality. We prove that such spaces are either Gromov-hyperbolic or have polynomial growth. As an application we prove that 2-dimensional Poincaré duality groups over commutative rings are commensurable with surface groups.

Incidence Matrices of Projective Planes and of Some Regular Bipartite Graphs of Girth 6 with Few Vertices
Let q be a prime power and r = 0, 1 . . . , q − 3. Using the Latin squares obtained by multiplying each entry of the addition table of the Galois field of order q by an element distinct from zero, we obtain the incidence matrices of projective planes and the incidence matrices of (q− r)-regular bipartite graphs of girth 6 and q − rq− 1 vertices in each partite set. Moreover, in this work two La...
متن کاملType-2 Fuzzy Arithmetic using Alpha-planes
This paper examines type-2 fuzzy arithmetic using interval analysis. It relies heavily on alpha-cuts and alpha-planes. Furthermore, we discuss the use of quasi type-2 fuzzy sets proposed by Mendel and Liu and define quasi type-2 fuzzy numbers. Arithmetic operations of such numbers are defined and a worked example is presented. Keywords— Fuzzy Arithmetic, Type-2 Fuzzy Arithmetic, Type-2 Fuzzy Nu...
متن کاملCamera Calibration from the Quasi-affine Invariance of Two Parallel Circles
In this paper, a new camera calibration algorithm is proposed, which is from the quasi-affine invariance of two parallel circles. Two parallel circles here mean two circles in one plane, or in two parallel planes. They are quite common in our life. Between two parallel circles and their images under a perspective projection, we set up a quasi-affine invariance. Especially, if their images under...
متن کاملInstitute for Mathematical Physics Intermediate Inversion Formulas in Integral Geometry Intermediate Inversion Formulas in Integral Geometry
We solve the following \intermediate" problem of integral geometry: to reconstruct integrals of a function over p-dimensional planes in R n starting from its integrals over k-planes, where p < k. Some generalizations are also presented.
متن کاملCircle Geometry and Three–Dimensional Subregular Translation Planes
Algebraic pencils of surfaces in a three–dimensional circle geometry are used to construct several infinite families of non-André subregular translation planes which are three–dimensional over their kernels. In fact, exponentially many such planes of a given order are constructed for both even and odd characteristic.
