The partition function defined in the usual way is a gauge-dependent quantity. However, the ansatz of Bernard and Gross et al leaves it gauge invariant. We use this ansatz for the partition function to show that Lagrange multipliers (non-physical bosonic fields) are not restricted to satisfying any boundary conditions in the path integral at finite temperature. We take a quantum mechanical model to illustrate that boundary conditions satisfied by non-physical fields depend on the choice of 'gauge'.

On verification of restricted extended affine equivalence of vectorial boolean functions Sınak, Ahmet; Özbudak, Ferruh; Yayla, Oğuz; Department of Cryptography (2012) Vectorial Boolean functions are used as S-boxes in cryptosystems. To design inequivalent vectorial Boolean functions resistant to known attacks is one of the challenges in cryptography. Verifying whether two vectorial Boolean functions are equivalent or not is the final step in this challenge. Hence, finding a fast technique for determining whether two given vectorial Boolean functions are equivalent is an important problem. A special class of the equivalence called restricted extended affine (REA) equivale...
An overview of trace based public key cryptography over finite fields Akyıldız, Ersan (2014-03-15) The Discrete Log Problem (DLP), that is computing x, given y = alpha(x) and (alpha) = G subset of F-q*, based Public Key Cryptosystem (PKC) have been studied since the late 1970's. Such development of PKC was possible because of the trapdoor function! : Z(l) -> G = (alpha) subset of F-q*, f (m) = alpha(m) is a group homomorphism. Due to this fact we have; Diffie Hellman (DH) type key exchange, EIGamal type message encryption, and Nyberg-Rueppel type digital signature protocols. The cryptosystems based on th...
Some New Bounds on Closed Ordinal Ramsey Numbers Sağlam, Irmak; Kaya, Burak; Department of Mathematics (2020-12-22) Partition calculus on ordinals was introduced by Erd ̋os and Rado and is a well-studiedsubject. Later on, Baumgartner extended this investigation to topological spaces andstudied topological partition relations on ordinal spaces.In recent years, closed and topological partition relations on ordinals have been anactive area of research. This thesis is a contribution to the study of closed ordinalRamsey numbers. More specifically, we provide new lower and upper bounds forclosed ordinal Ramsey numbers of p...
A NEW METHOD FOR HARMONIC RESPONSE OF NONPROPORTIONALLY DAMPED STRUCTURES USING UNDAMPED MODAL DATA Özgüven, Hasan Nevzat (Elsevier BV, 1987-09-08) A method of calculating the receptances of a non-proportionally damped structure from the undamped modal data and the damping matrix of the system is presented. The method developed is an exact method. It gives exact results when exact undamped receptances are employed in the computation. Inaccuracies are due to the truncations made in the calculation of undamped receptances. Numerical examples, demonstrating the accuracy and speed of the method when truncated receptance series are used are also presented. ...
A note on b-weakly compact operators Alpay, Safak; Altin, Birol (Springer Science and Business Media LLC, 2007-11-01) We consider a continuous operator T : E -> X where E is a Banach lattice and X is a Banach space. We characterize the b-weak compactness of T in terms of its mapping properties.
