On minimal λco-open sets
No full textWe introduce and discuss the notions of minimal λco-open sets in topological spaces. We establish some of it basic fundamental properties of minimal λco-open. We show that the notions of minimal open sets and minimal λco-open are independent and finally we obtain some application of a minimal λco-open sets.ROSAS, ENNIS-will be generated-orcid-0000-0001-8123-9344-60
Weakly (I, J)-continuous multifunctions and contra (I, J)-continuous multifunctions
No full textThe purpose of the present paper is to introduce, study
and characterize upper and lower weakly (I, J)-continuous multifunctions and contra (I, J)-continuous multifunctions.
Also, we investigate its relation with another class of continuous multifunctions.

On real valued ω-continuous functions
No full textThe aim of this paper is to introduce and study upper and
lower !-continuous functions. Some characterizations and several proper-
ties concerning upper (resp. lower) !-continuous functions are obtained.Carpintero, Carlos-a355945f-e98f-41c1-bf2e-c139d8aa37cb-0Rajesh, N.-4507320c-a2f2-4c9e-8ab4-7896d97c6957-0Rosas Rodriguez, Ennis Rafael-0000-0001-8123-9344-60
Θ-modifications on weak spaces
No full textIn this article, we want to study and investigate if it is
possible to use the notions of weak structures to develop a new theory
of - modi cations in weak spaces and study their properties, nally we
study some forms of weak continuity using this modi cations.Rosas Rodriguez, Ennis Rafael-0000-0001-8123-9344-600Carpintero, C.-123dd2ec-abe0-436e-89d9-7cab6b66f31e-0Sanabria, J.-83af4f85-486c-4d16-997f-b742c5929f24-
On λ D − R0 And λ D − R1 Spaces
No full textIn this paper we introduce the new types of separation axioms called λ D − R0 and λ D − R1 spaces, by using λ D-open set. The notion λ D − R0 and λ D − R1 spaces are introduced and some of their properties are investigated.namiq, sarhad-will be generated-orcid-0000-0001-8747-2542-600ROSAS, ENNIS-will be generated-orcid-0000-0001-8123-9344-60
New types of locally connected spaces via clopen set
No full textIn this paper, we define and study a new type of connected spaces called λco-connected space. It is remarkable that the class of λ-connected spaces is a subclass of the class of λco-connected spaces. We discuss some characterizations and properties of λco-connected spaces, λco components and λco-locally connected spaces.ROSAS, ENNIS-will be generated-orcid-0000-0001-8123-9344-600namiq, sarhad-will be generated-orcid-0000-0001-8747-2542-60
Almost contra (i, j)-continuous multifunctions
No full textThe purpose of the present paper is to introduce, study
and characterize the upper and lower almost contra (I, J)-continuous
multifunctions. Also, we investigate its relation with another well known
class of continuous multifunctions.Rosas, Ennis-c145ef77-57b4-4c48-a23b-bd05bfbc6248-600Carpintero, Carlos-a355945f-e98f-41c1-bf2e-c139d8aa37cb-600Sanabria, José-d0d4bf22-e06b-4b65-9c66-b0cbd76bf5a8-60
ADA President 1951-1952: LeRoy Massey Ennis
No full textDoctor Ennis, of Philadelphia, became the eighty-eighth president of the Association at the 1951 meeting in Washington. In his presidential address at the 1952 meeting, Doctor Ennis spoke of the rapid institution of fluoridation of public water supplies since it was approved by the House of Delegates in 1950. Doctor Ennis was a professor and chairman of the department of radiology for over 40 years at the University of Pennsylvania School of Dental Medicine. He was the author of a textbook, Dental Roentgenology, and was a founder and president of the American Academy of Dental Radiology. Doctor Ennis served as president of the Pennsylvania Dental Association. He was born in Pennsylvania in 1893 and died in 1978
Sobre las descomposiciones de continuidad usando bioperaciones
No full textEn este espacio propiciado por el Departamento de Ciencias Naturales y Exactas, primeramente se habla un poco sobre la historia de las descomposiciones y se explica porqué los conjuntos abiertos generalizados juegan un papel importante en topología general y ha sido un tópico de interés
para muchos matemáticos. El objetivo principal fue introducir nuevos conjuntos usando bioperaciones y encontrarrelaciones entre ellas.Departamento de Ciencias Naturales y ExactasSchnorr, Carlos Eduardo-will be generated-orcid-0000-0002-2047-2107-600ROSAS, ENNIS-will be generated-orcid-0000-0001-8123-9344-60
Bioperation approach to Przemski's decomposition theorems
No full textPrzemski introduced D(?, s)-set, D(?, b)-set, D(p, sp)-set, D(p, b)- set and D(b, sp)-set to obtain several decompositions of continuity. In this paper, we extend these sets via bioperation and obtain new decompositions of continuity.Carpintero, Carlos-will be generated-orcid-0000-0003-3831-952X-600Nirmala, Rajendren-will be generated-orcid-0000-0003-0114-6370-600Rajesh, N.ROSAS, ENNIS-will be generated-orcid-0000-0001-8123-9344-60
