    Notes: Summary We introduce a new Skorohod topology for functions of several variables. Since ann-variable function may be viewed as a one-variable function with values in the set of (n−1)-variable functions, this topology is defined by induction from the classical Skorohod topology for one-variable functions. This allows us to define the notion of completen-parameter symmetric Markov processes: Such processes are, for any 1≤p≤n, rawp-parameter Markov processes (in the sense of our previous paper [17]) with values in the space of (n−p)-variable functions. We prove, for these processes and their Bochner subordinates, a maximal inequality which implies the continuity of additive functionals associated with finite energy measures. We finally present several important examples.

    Markov properties of multiparameter processes and capacities (1995)

    Notes: Summary We study a class of multiparameter symmetric Markov processes. We prove that this class is stable by subordination in Bochner's sense. We show then that for these processes, a probabilistic and an analytic potential theory correspond to each other. In particular, additive functionals are associated with finite energy measures, hitting probabilities are estimated by capacities, quasicontinuity corresponds to path-continuity. In the last section, examples show that many earlier results, as well as new ones, in this domain can be obtained by our method.

    Notes: Abstract. Background: Diffuse peritoneal tumor infiltration is well recognized on computed tomography (CT) and is usually associated with carcinomatosis. The purpose of this investigation was to analyze the CT findings of peritoneal spread from primary gastrointestinal lymphomas. Methods: Abdominal CT scans in eight patients with peritoneal lymphomatosis were retrospectively reviewed. Patients were 12–75 years old (mean = 48 years); with six patients were male and two were female. Pathologic evidence of primary lymphoma was available by colonoscopic biopsy of the terminal ileum in seven cases and by gastroscopic biopsy of the stomach in one case. All patients had non-Hodgkin's lymphoma. We analyzed CT findings in view of presence or loculation of ascites, abnormal patterns of mesentery and omentum, presence of peritoneal enhancement, presence of low attenuation and location of lymph nodes, and primary gastrointestinal lymphoma. Results: Although ascites was present in all patients, there was no loculation. The involvement of mesentery was present in seven patients, and the stellate pattern was the common type (4/7). The involvement of omentum was present in seven patients, and the common type was omental cake (3/7). Peritoneal enhancement was present in six patients. Enlarged lymph nodes were present in six patients, mainly at the retroperitoneum and mesentery, and showed centrally low attenuation in half the patients. Conclusion: Patterns of tumor involvement of mesentery, omentum, and peritoneum seen in peritoneal lymphomatosis are indistinguishable from those seen in peritoneal carcinomatosis or tuberculous peritonitis. However, ascites without any loculation or septation and diffuse distribution of enlarged lymph nodes were helpful signs of peritoneal lymphomatosis.
