ISBN-13: 9780125113601

This e-book constitutes a primary- or second-year graduate path in operator idea. it's a box that has nice significance for different components of arithmetic and physics, resembling algebraic topology, differential geometry, and quantum mechanics. It assumes a easy wisdom in sensible research yet no earlier acquaintance with operator thought is needed.

Example text

Si f est directe, f est la compos´ee d’une rotation avec une homoth´etie de rapport k et de mˆeme centre. 2. Si f est indirecte, f est la compos´ee d’une sym´etrie orthogonale par rapport ` a une droite ∆ avec une homoth´etie de rapport k dont le centre est sur ∆. Preuve. Puisque k ̸= 1, f admet un point fixe O ∈ E. Soit h l’homoth´etie de centre O et de rapport k. Alors h−1 ◦ f est une isom´etrie admettant un point fixe O. 2 : – Si f est directe, alors h−1 ◦ f est positive et donc h−1 ◦ f =: r est une rotation de centre O.

Preuve. Puisque k ̸= 1, f admet un point fixe O ∈ E. Soit h l’homoth´etie de centre O et de rapport k. Alors h−1 ◦ f est une isom´etrie admettant un point fixe O. 2 : – Si f est directe, alors h−1 ◦ f est positive et donc h−1 ◦ f =: r est une rotation de centre O. Donc on a f = h ◦ r. – Si f est indirecte, alors h−1 ◦ f est n´egative et donc h−1 ◦ f =: s est une sym´etrie orthogonale par rapport `a une droite contenant O. On a alors f = h ◦ s. 3 Soit E un espace affine euclidien de dimension 3 et f une similitude de E de rapport k ̸= 1.

Si f est indirecte, alors h−1 ◦ f est n´egative et donc h−1 ◦ f = s est une sym´etrie orthogonale par rapport `a un plan contenantt O, soit antirotation. 3 Propri´ et´ es des similitudes dans le plan euclidien Dans toute cette partie, on se place dans le plan affine euclidien. 3. 1 Soit f une bijection affine alors les conditionns suivantes sont ´equivalentes : 1. f est une similitude 2. Pour tout triplet de points distincts A, B et C, on a ABC = f (A)f (B)f (C) 3. Pour tout quadrulet de points distincts A, B, C et D, si les droites (AB) et (CD) sont orthogonales alors les droites (f (A)f (B)) et (f (C)f (D)) le sont aussi.
