according to B&R, if Davidson had established his "no language" thesis, he would thereby have provided a decisive reason for abandoning the project he has long advocated--viz., that of trying to provide theories of meaning for natural languages by providing recursive theories of truth for such languages. For he would have shown that there are no languages to provide truth (or meaning) theories ...

In this paper, we describe the primitive ideal space of the $C^*$-algebra $C^*(mathcal G)$  associated to the ultragraph $mathcal{G}$. We investigate the structure of the closed ideals of the quotient ultragraph $  C^* $-algebra  $C^*left(mathcal G/(H,S)right)$ which contain no nonzero set projections and then we characterize all non gauge-invariant primitive ideals. Our results generalize the ...

‎We study $R$-groups for $p$-adic inner forms of quasi-split special unitary groups‎. ‎We prove Arthur's conjecture‎, ‎the isomorphism between the Knapp-Stein $R$-group and the Langlands-Arthur $R$-group‎, ‎for quasi-split special unitary groups and their inner forms‎. ‎Furthermore‎, ‎we investigate the invariance of the Knapp-Stein $R$-group within $L$-packets and between inner forms‎. ‎This w...

In this paper we investigate the Green‎ ‎graphs for the regular and inverse semigroups by considering the‎ ‎Green classes of them‎. ‎And by using the properties of these‎ ‎semigroups‎, ‎we prove that all of the five Green graphs for the‎ ‎inverse semigroups are isomorphic complete graphs‎, ‎while this‎ ‎doesn't hold for the regular semigroups‎. ‎In other words‎, ‎we prove‎ ‎that in a regular se...

This study aimed to analyze the factors affecting size of non-governmental organizations (NGOs) from a multinational perspective. Empirical analyses were conducted through econometric modeling, and data 17 countries 2003 2019 used. The was obtained World Bank OECD database. We used advanced panel estimation techniques (CUP-FM CUP-BC) obtain long-run coefficients. GDP per Capita, general governm...
