Pdf Remarks On Fixed Point Theorems Of Ricceri

Pdf Remarks On Fixed Point Theorems Of Ricceri In the present paper, we deduce some fixed point theorems for [0, 1] spaces from ricceri’s alternative principle. even though these theorems are consequences of known theorems for an interval [a. Thus, the conclusion follows. finally, we would like to point out that that our noncompact fixed point theorems 4.1 and 4.2 are different from all other noncompact fixed point theorems in the literature. for other kinds of fixed point theorems for lower semicontinuous mappings in banach spaces, the reader may consult ]17,18]. references 1. d.

Pdf Relation Theoretic Coupled Fixed Point Theorems Pdf | in may 2017, ricceri sent me a theorem and asked me whether it is well known or not. i replied that i did not know. remarks on fixed point theorems of ricceri, proc. '97 workshop on math. These results generalize and improve many well known results in the literature, i.e., [1,4 10,14,15]. in particular, our new fixed point theorems improve the well known fan glicksberg fixed point theorem. now we recall and introduce some notations. let e be a vector space and a c e. we shall denote by coa the convex hull of a. Abstract. some remarks on a strict minimax inequality, which plays a fundamental role in ricceri's three critical points theorem, are presented. as a consequence, some recent applications of. In this paper, using a recent result by j. saint raymond ([6]), we improve the three critical points theorem established in [5]. article pdf download to read the full article text.

The results, in their corrected form, still bring about noted improvements over a multitude of relevant fixed point theorems of the existing literature, substantiating the utility of these (two) new notions. in an interesting article, bouhadjera and godet thobie (2009) [6] introduced notions of subcompatibility and subsequential continuity, and. Of rn and a proof of brouwer’s fixed point theorem using the degree theory established is just one of the results presented. the second half of the chapter looks at the degree of a map defined on a normed linear space and here an alternative proof of schauder’s fixed point theorem using degree theory is illustrated.
