"The Lebesgue constants on projective spaces", Turkish Journal of Mathematics, Vol. 45, No. 2, pp. 856-863.1300-00981303-6149https://search.trdizin.gov.tr/en/yayin/detay/443558/the-lebesgue-constants-on-projective-spacesWe give the solution of a classical problem of Approximation Theory on sharp asymptotic of the Lebesgueconstants or norms of the Fourier-Laplace projections on the real projective spaces Pd(R). In particular, these resultsextend sharp asymptotic found by Fejer [2] in the case of S1in 1910 and by Gronwall [4] in 1914 in the case of S2. Thecase of spheres, Sd, complex and quaternionic projective spaces, Pd(C), Pd(H) and the Cayley elliptic plane P16(Cay)was considered by Kushpel [8].eninfo:eu-repo/semantics/openAccessMatematikArticle4528568632-s2.0-85103726765WOS:000634389600014443558Q2Q2
