OBJECTIVES Lip lesions are a frequent cause of consultation in dentistry, as they comprise a significant proportion of the oral lesions. The aim of the present study was to identify the different lip lesions and determine their prevalence in an Indian population. MATERIAL AND METHODS 5231 patients visiting a Department of Oral Medicine and Radiology were examined for the presence of different...

the object of this paper to derive certain sucient condi-tions for close-to-convexity of certain analytic functions dened on theunit disk

We consider certain properties of f(z)f ′′(z)/f ′2(z) as a sufficient condition for starlikeness.

We study the quantum integrability of the O(N) Nonlinear σ (nlσ) model and the O(N) Gross-Neveu (GN) model on the half-line. We show that the nlσ model is integrable with Neumann, Dirichlet and a mixed boundary condition and that the GN model is integrable if ψ a + | x=0 = ±ψ a − | x=0. We also comment on the boundary condition found by Corrigan and Sheng for the O(3) nlσ model. 1 Work done und...

INFINITE LOCALLY FINITE GROUPS OF TYPE PSL(2, K) OR Sz(K) ARE NOT MINIMAL UNDER CERTAIN CONDITIONS JAVIER OTAL AND JUAN MANUEL PENA In classifying certain infinite groups under minimal conditions it is needed to find non-simplicity criteria for the groups under consideration . We obtain some of such criteria as a consequence of the main result of the paper and the classification of finite simpl...

In this paper, we consider some sufficient conditions for two integral operators to be starlike, close-to-convex and uniformly convex functions defined in the open unit disk. Mathematics subject classification (2000): 30C45.

In this paper, we determined conditions on β, αi and fi(z) so that the integral operator { β ∫ z 0 tβ−1 n ∏ i=1 ( fi(t) t ) 1 αi dt } 1 β is univalent in the open unit disk for the two subclasses analytic functions. 2000 Mathematical Subject Classification: Primary 30C80, Secondary 30C45.
