چکیده
1.1 Notation In this note, N denotes the set of non-negative integers, i.e. N = {0, 1, 2, . . . }. Let V be a C-linear space and z a formal variable. We introduce the following linear spaces: V [z] := {n∈N vnz | vn ∈ V, vn = 0 for all but finitely many n}, V [z, z−1] := {n∈Z vnz | vn ∈ V, vn = 0 for all but finitely many n}, V [[z]] := {n∈N vnz | vn ∈ V }, V [[z, z−1]] := {n∈Z vnz | vn ∈ V }, V ((z)) := {n∈Z vnz | vn ∈ V, vn = 0 if n ¿ 0}, V {z} := {r∈C vrz | vr ∈ V, vr = 0 if Re(r) ¿ 0}.

On the analytic properties of intertwining operators I: global normalizing factors
We provide a uniform estimate for the $L^1$-norm (over any interval of bounded length) of the logarithmic derivatives of global normalizing factors associated to intertwining operators for the following reductive groups over number fields: inner forms of $operatorname{GL}(n)$; quasi-split classical groups and their similitude groups; the exceptional group $G_2$. This estimate is a key in...
متن کاملCaractérisation des paramètres d'Arthur, une remarque
In The endoscopic classification of representations, J. Arthur has proved the Langlands' classification for discrete series of p-adic classical groups. This uses endoscopy and twisted endoscopy. In this very short note, we remark that the normalization $rmgrave{a}$ la Langlands-Shahidi of the intertwining operators, allows to avoid endoscopy. This is based on the intertwini...
متن کاملOrdered Weighted Averaging Operators and their Generalizations with Applications in Decision Making
The definition of ordered weighted averaging (OWA) operators and their applications in decision making are reviewed. Also, some generalizations of OWA operators are studied and then, the notion of 2-symmetric OWA operators is introduced. These generalizations are illustrated by some examples.
