A predicative semantics is a mapping of programs to predicates These pred icates characterize sets of acceptable observations The presence of time in the observations makes the obvious weakest xed point semantics of itera tive constructs unacceptable This paper proposes an alternative We will see that this alternative semantics is monotone and implementable feasible Fi nally a programming theor...
in this paper, we introduce a new concept of - -ϕ-contractive integral type mappings and establish some new xed point theorems in complete metric spaces.
The Agilent 1260 Infi nity Analytical Supercritical Fluid Chromatography (SFC) System provides LC-like sensitivity and UHPLC power range. It is a pressurized system that has a fi xed-loop autosampler. The injection loops come in different sizes to perform fi xed-loop injections. Injecting a volume smaller than the loop volume is possible using the partial loop-fi ll injection method where the l...
Suspensory fi xation devices in anatomic anterior cruciate ligament (ACL) reconstruction commonly feature a button that rests on the cortex of the femur, and a loop that holds the graft in position until healing can occur. While this loop can be closed and fi xed in length, some contemporary designs feature a loop that is adjustable. The purpose of this study was to assess the displacement of t...
We discuss the temporal logic`USF', involving Until, Since and the xed point operator ' of Gabbay, with semantics over the natural numbers. We show that any formula not involving Until is equivalent to one without nested xed point operators. We then prove that USF has expressive power matching that of the monadic second-order logic S1S. The proof shows that any USF-formula is equivalent to one ...
Let Q IFP be any quantiier such that FO(Q IFP), rst order logic enhanced with Q IFP and its vectorizations, equals inductive xed point logic, IFP in expressive power. It is known that for certain quantiiers Q, the equivalence FO(Q IFP) IFP is no longer true if Q is added on both sides 12, 13]. Rather, we have FO(Q IFP ; Q) < IFP(Q) in such cases. We extend these results to a great variety of qu...
Let (x n) and (^ x n) be two vector sequences converging to a common limit. First, we shall deene nonlinear hybrid procedures which consist of constructing a new vector sequence (y n) with better convergence properties than (x n) and (^ x n). Then, this procedure is used for accelerating the convergence of a given sequence and applied to the construction of xed point methods. New methods are de...
Recently, Piri and Kumam [Fixed Point Theory and Applications 2014, 2014:210] improved concept of F -contraction and proved some Wardowski and Suzuki type xed point results in metric spaces. The aim of this article is to de ne generalized GF -contraction and establish Wardowski and Suzuki type xed point results in metric and ordered metric spaces and derive main results of Piri et al. as coro...
in this paper, stochastic generalizations of some fixed point for operators satisfying random contractively generalized hybrid and some other contractive condition have been proved. we discuss also the existence of a solution to a nonlinear random integral equation in banah spaces.
In the 1920s, algebraic topology began to develop partially due to the need for new topological techniques in solving problems in xed point theory. Indeed, the celebrated Lefschetz xed point theorem is a far reaching generalization of the well-known Brouwer xed point theorem. The eld of topological xed point theory continued to ourish through the 1940s during which much of the foundations was l...
