we study umbilic (space-like) submanifolds of pseudo-riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo euclidean space and relate this notion to umbilicity. finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.a pseudo-riemannian submanifold m in (a ps...

The aim of this paper is to introduce the notion of commutative pseudo BE-algebras and investigate their properties.We generalize some results proved by A. Walendziak for the case of commutative BE-algebras.We prove that the class of commutative pseudo BE-algebras is equivalent to the class of commutative pseudo BCK-algebras. Based on this result, all results holding for commutative pseudo BCK-...

Os autores fazem o relato de três casos clínicos: Papilomatose florida, Epitelioma cuniculatum e Condiloma gigante Buschke Lowenstein, considerados como representativos entidades que compõem grupo das Papilomatoses pseudo-carcinomatosas. São favoráveis à conceituação pseudo-carcinomatosas apoiando-se na semelhança clínica, histopatológica, evolutiva da terapêutica a ser instituída. Discutem, ai...

In this paper, we study the theory of pseudo knots, which are knots with some missing crossing information, and introduce tied links knotoids. particular, first present a braiding algorithm for then L-moves in that setting, use formulate sharpened version analogue Markov theorem braids. Then, links, generalize notion exploit relation between singular links. We an L-move braid equivalence monoid...

Pseudo-Pseudo-Myocardial Infarction To the Editor: Hung and colleagues1 present a very important example of a pseudo-infarction pattern presumably related to pancreatitis, one of several clinical situations in which thrombolytic therapy is either not indicated or contraindicated. I am intrigued by the pattern of the bizarre T waves in the limb leads and wonder if part or all of this phenomenon ...
