A New Approach to the Lenard-Magri Scheme of Integrability
We develop a new approach to the Lenard-Magri scheme of integrability of bi-Hamiltonian PDEs, when one of the Poisson structures is a strongly skew-adjoint differential operator

DR. REFİK SAYDAM (1882-1942)
Born in Istanbul in 1882, Dr. İbrahim Refik Saydam graduated from the Military Medical School in 1905 with the rank of "Captain". Following his successful performance in the Balkan Wars, with the beginning of World War I, he was appointed as Deputy General Inspector of General Headquarters Sahra Sanitary and continued his duty until the signing of the Armistice of Mudros. IX. He actively participated in the War of Independence process as a member of the delegation that went to Samsun with Mustafa Kemal Pasha in the capacity of "Army Inspector, Deputy Chief of Sanitary Affairs" and served as "Deputy of Sanitary and Civil Aid" between 10 March 1921 and 20 December 1921. Dr. was appointed to the same position again during the Republic period. Dr. Saydam continued his duty from March 4, 1925 to October 25, 1937, and organized successful organizations that maintain their impact today in the establishment of health infrastructure and the fight against infectious diseases. He passed away on July 8, 1942, while he was on duty

Symmetry classification of two component burgers systems with nondiagonalizable main coefficient matrix
İki bileŞenli Burgers tipi anakatsayısı köŞegenleŞtirilebilir olmayan ve belirli bir ağırlıkŞemasına göre homojen denklem sistemleri yüksek simetri varlığına göre sınıflandırıldı.İkinci dereceden sistemlerin üçüncü dereceden, üçüncü dereceden sistemlerin beŞinci derecedensimetrilerinin varlığı araŞtırıldı. Yüksek simetri olduğu belirlenen sistemler ayrıcayüksek korunum kanunları için de araŞtırıldı.Bulunan oniki yeni yüksek simetrili sistemden altısının yüksek korunum kanunu da olduğu gözlendi. Sadece yüksek simetrili olan sistemlerin master simertileri araŞtırıldı.Yüksek korunum kanunlu sistemlerin Magri Şemalarının kurulması için yapı iŞlemcileri araŞtırıldı.Two component Burgers type of systems with nondiagonalizable main matrix which arehomogeneous in a certain weighting scheme are classified for existence of a higher symmetry.Second order systems are searched for existence of a third order, third order systemsare searched for existence of a fifth order symmetry. Systems obtained to possess ahigher symmetry are further investigated for higher conservation laws.Out of twelve newly obtained systems possessing hihger symetry, six are observed to possesshigher conservation law also. Systems with only higher symmetries are investigatedfor their master symmetries. Systems with higher conservation laws are investigated fortheir structure operators to construct Magri scheme
Multi-hamiltonian integrability in dynamical systems
Bu çalışmada kanonik Hamiltonsal yapıdan başlanılarak Poisson yapıları ve bu yapılara sahip çoklu-Hamiltonsal dinamik sistemlerin tamamen entegre edilebilirliği gözden geçirilmiştir. Çoklu-Hamiltonsal entegre edilebilir olduğu bilinen bazı dinamik sistemler derlenmiştir.In this study, starting from the canonical Hamiltonian structure, Poisson structures and complete integrability of the dynamical systems possessing multi-Hamiltonian structures are reviewed. Some dynamical systems which are known to be multi-Hamiltonian integrable are also compiled

On integrability of some bi-Hamiltonian two field systems of partial differential equations
We continue the study of integrability of bi-Hamiltonian systems with a compatible pair of local Poisson structures (H0, H1), where H0 is a strongly skew-adjoint operator. This is applied to the construction of some new two field integrable systems of PDE by taking the pair (H0, H1) in the family of compatible Poisson structures that arose in the study of cohomology of moduli spaces of curves
A class of nonautonomous coupled KdV systems
A class of nonautonomous coupled Korteweg-de Vries (KdV) systems in (1+1) dimensions are considered for integrability classification. Integrability of the systems is associated with the existence of a certain recursion operator. Some new integrable nonautonomous two-component KdV systems are found.
